Proxy Server Automatic Switching
This article applies to registered Standard and PRO versions of the Proxy Switcher.
Proxy Switcher has two automatic proxy switching modes:
Keep Alive
Auto Switching
Keep-Alive mode
Keep Alive mode works passively, it continuously checks currently active proxy server. If an error is returned
Proxy Switcher will start looking for a working server in the folder named “ProxySwitcher”. When such server is found an automatic proxy
change will be performed.
This mode is most suited in cases where you have relatively small amount of personal proxy servers. For example in case you bought
a list of private (password protected) proxy servers.
Auto Switching mode
Automatic proxy switching is based on an active proxy scanner, alive checker and switching timer. Which means that besides doing what Keep-Alive mode
does Auto Switcher builds a queue of working proxy servers.
This queue is continously filled and verified in the background.
If program finds that current proxy server has stopped responding to the requests
an automatic switch will be made to one of the servers from the queue. Which means nearly instant switch to next server.
Which in turn results in all the subsequent connections to be made via new proxy server. Last part of the system is a periodic
switching timer which user can adjust. When timer triggers it will issue an automatic switching request.
Timer can be set from 10 seconds to 30 minutes.
Troubleshooting Auto Switching
Sometimes the queue does not want to fill up at all. There are a few possible causes:
There are no servers in the folders set as source folders for automatic switching.
There are servers in source folders but they fail to be tested as working ones:
Proxy servers are not working.
You have changed test targets and as a result it’s not working (there are few differences/bugs depending on the version you use. )
Servers are not being tested as working due to some other reasons.
If you are using recent version of the program you can enable display of the scanning error messages in the auto-switching log.
This will give you hints (error messages why the queue is not filling up).
Tuning
You can change the switching perefences from popup menu under the button “X”. By default it prefers servers with faster response times.
It can be changed to pure random, weighted random, random with preference of less used servers or sequential (alphabetic).
Only SSL servers option will force switching to pick only servers that support connections. This option is enabled by default.
To issue an immediate switching request you can press on a button with an →. Also a global hotkey can be set which when pressed will issue an immediate switching request.
When such a switch is completed a balloon hint will be shown in the tray with the address and location of the new proxy server.
This hotkey can be set from the program’s preferences.

Automatic proxy detection is a process by which a Web proxy server is identified by the system and used to send requests on behalf of the client. This feature is also known as Web Proxy Auto-Discovery (WPAD). When automatic proxy detection is enabled, the system attempts to locate a proxy configuration script that is responsible for returning the set of proxies that can be used for the request. If the proxy configuration script is found, the script is downloaded, compiled, and run on the local computer when proxy information, the request stream, or the response is obtained for a request that uses a WebProxy instance.
Automatic proxy detection is performed by the WebProxy class and can employ request-level settings, settings in configuration files, and settings specified using the Internet Explorer Local Area Network (LAN) dialog box.
Note
You can display the Internet Explorer Local Area Network (LAN) Settings dialog box by selecting Tools from the Internet Explorer main menu and then selecting Internet Options. Next, select the Connections tab, and click LAN Settings.
When automatic proxy detection is enabled, the WebProxy class attempts to locate the proxy configuration script as follows:
The WinINet InternetQueryOption function is used to locate the proxy configuration script most recently detected by Internet Explorer.
If the script is not located, the WebProxy class uses the Dynamic Host Configuration Protocol (DHCP) to locate the script. The DHCP server can respond either with the location (host name) of the script or with the full URL for the script.
If DHCP does not identify the WPAD host, DNS is queried for a host with WPAD as its name or alias.
If the host is not identified and the location of a proxy configuration script is specified by the Internet Explorer LAN settings or a configuration file, this location is used.
Applications running as an NT Service or as part of use the Internet Explorer proxy server settings (if available) of the invoking user. These settings may not be available for all service applications.
Proxies are configured on a per-connectoid basis. A connectoid is an item in the network connection dialog, and can be a physical network device (a modem or Ethernet card) or a virtual interface (such as a VPN connection running over a network device). When a connectoid changes (for example, a wireless connection changes an access point, or a VPN is enabled), the proxy detection algorithm is run again.
By default, the Internet Explorer proxy settings are used to detect the proxy. If your application is running under a non-interactive account (without a convenient way to configure IE proxy settings), or if you want to use proxy settings different than the IE settings, you can configure your proxy by creating a configuration file with the
For requests that you create, you can disable automatic proxy detection at the request level by using a null Proxy with your request, as shown in the following code example.
public static void DisableForMyRequest (Uri resource)
{
WebRequest request = (resource);
= null;
WebResponse response = tResponse ();}
Public Shared Sub DisableForMyRequest(ByVal resource As Uri)
Dim request As WebRequest = (resource)
= Nothing
Dim response As WebResponse = tResponse()
End Sub
Requests that do not have a proxy use your application domain’s default proxy, which is available in the DefaultWebProxy property.

How to Automatically Switch Proxies From a List of IPs
If you’ve come to this article it means you’re using proxies. Congratulations. How’s all that anonymity treating you? It also means that you probably have multiple proxies, and it’s getting pretty laborious to switch between them manually. I get it. Proxies take time and energy to use correctly, and that’s without loading them up and clicking on each one ’s a better way to switch proxies. Whether you’re using a couple of proxies to browse anonymously or massive batches to scrape data, you should not be clicking on a different proxy every time you want to use one. I’ll explain three main methods for automatically switching your proxies. They’re all pretty easy and some of them are free! Browser Proxy SwitchersThe browser in this sense means a web browser, which should be pretty obvious to you proxy savvy people. Browser switchers are very helpful because a lot of the time proxies are used by individuals in a casual way; people that just want to protect their anonymity, have purchased a small batch (or use free proxies), and need to switch between times our web browser is where we’ll update proxy settings. Sometimes you have to update it in the networking settings of your OS, but if you want a single browser to use a single proxy or switch between a number of them, you’re going to need an extension. Extensions are downloaded from web stores and are specific to individual browsers, like Chrome and Firefox. Extensions number in the thousands and do all sorts of things. These extensions will make switching proxies super added a list for switching proxy chrome extension checking out the extensions of a specific browser, you’ll want to search for “proxy switchers. ” A ton of options will come up, especially in a popular browser like Chrome. If you’ve had any experience with this in app stores, it’s the same concept. People upload countless extensions—some of them are good, some are terrible. Make proxy switcher extension decisions based on reviews, how often the software gets an update (also called support), and how easy it is to technology, in general, can get dicey quickly, so you’ll want a trusted proxy switcher to be handling your proxies. I’ve also selected a couple of well known extension-based proxy switchers for, note that this method will work for roughly 2-15 proxies. It’s best for the person that just likes to browse the internet anonymously, as opposed to scraping data with large xyProxyNamed after the adorable, swirling-tailed Firefox browser, FoxyProxy is probably the most common and long-lasting extension for easily switching proxies. Today it works with both Chrome and Firefox; you’re probably using one of those two browsers, or can, so this is a pretty universal of the downfalls with browser extensions is that you have to use the browser the extension is available on, so shop around for what’s best for xyProxy Standard is recommended, though the Basic version is available for simpler users that don’t want bells and whistles. Both are free, and both can be added with a single FoxyProxy Standard you’ll receive an extension that allows you to easily upload all your proxy IP addresses and switch between them at will. You do this with a simple click, and the browser will start browsing the internet with the proxy you’ve just of you might be thinking, “Uh, that’s not automatic at all. You’re still clicking! ” Those of you thinking such things are spoiled and are clearly used to technology solving all of your problems. You’re also right, of xyProxy Standard can perform more complex functions, the most important of which is automating the proxy switching. You can set a number of rules for automatic switching. They can be set to automatically switch based on what website you’re visiting or for different types of proxies. This allows a SOCKS proxy and HTTP proxy to be employed at different times, depending on your browsing xyProxy functions a little differently in Chrome and Firefox, and it’s really built for Firefox. In that browser, it provides helpful color-changing bars to indicate your proxies’ strength, has clear tabs for changing specific settings, and is accessed Chrome FoxyProxy melts into the Chrome API, which is nice, but it’s not quite as user friendly. Still, the functionality is great — there are lots of updates and help and you can switch through your proxies SwitchySharpAs you’ll begin to see, there are a ton of options in the Chrome web store. Proxy SwitchySharp is one of the most reviewed and is actually a ported project from SwitchyPlus, a well-known extension proxy switcher that stopped receiving Switchyaharp also works within Chrome’s API and allows you to switch proxy to use in a single click. You can do it manually, but you can also set up rules for switches to occur at specific times or user interface for Proxy SwitchySharp is well designed, and you’ll be able to do a lot of complex, scenario-based functions with this OptionUnfortunately for users of Safari, there aren’t any extensions that allow you to easily or automatically switch can always use Chrome or Firefox on a Mac to get through this issue, but I’m all about providing you with does have a method of easy proxy switching, though it won’t ever be “automatic. ” To do this, you’ll need to be able to access your Network settings in Mac OS System Preferences. Once there, find the “Location” drop-down menu (it’s at the top). It will likely say “Automatic, ” which is not at all the type of automatic we are looking on this to “Edit Locations, ” which will open up a screen that allows you to add, subtract, and edit new locations. Essentially, you create a Location for every proxy you have. This will allow you to have a custom setting for each this by naming the Location so you’ll remember which proxy it is, then head over to the “Advanced” button in the same network panel. In the “Advanced” section head to Proxies; you’ll find a number of types of proxies that can be entered, including the authentication methods. Select the type of proxy you are using, enter the IP address and port, click “Ok, ” then click “Apply. ”Do this for every proxy you want to use in Safari. After this, you can click on the Apple button in the top left of your screen (not in Safari itself), and you’ll see the option for Location under System of your entered locations will be there, and you can select one to use at any time. This routes all your web traffic (or all your traffic, if you have a SOCKS proxy) through the selected to Set Up Proxy in Safari for macOSSoftwareThe next category for easy and automatic proxy switching is software. This is a massive category and will effectively switch your proxies for you while also performing a whole bunch of other tasks. There are many tiers of software, from free open source options to paid-for applications. I’ll touch base on two main tProxy Switcher is a well-named software application that will switch your proxies with the best of ‘em. The program is free, went open-source in 2014, and all of its files can be found on GitHub. The open-source junkies reading should stop here, because this is the resource you Switcher works for Windows 7, 8 and 10. Its technology allows it to auto-detect a network connection and executes “actions” based on that connection. Actions are the term for specific protocols the program follows, like automatically adjusting proxy settings in Internet browsers. The product ships with default actions for Internet Explorer, Firefox, and Opera, so if you use one of those browsers it’ll be really simple to ’s a well-used resource, which means many people have created other Actions for other web browsers, and you can create your own Actions. That will require some know-how, of rapeBoxIf you’re getting into the world of proxies and have enough that you need to switch them frequently, you either need to know about ScrapeBox, or you’ve already heard of it. The tool is primarily used for scraping large batches of domain data, but it’s really a jack of all tradesMost of the previous examples were about basic users wanting to automatically adjust proxy use based on internet browsers. This is great if you have 5 proxies and just want to adjust which one is being used at a given rapeBox is more for the power user and takes everything to a whole new level. The basic function of ScrapeBox is that you enter in a list of proxies, then execute certain complex data scraping actions with those proxies. ScrapeBox is built to use both free public proxies and private proxies, so you can enter in massive lists without an the Harvester on Your ScrapeBox Isn’t Working10+ Free Proxy List – IP:PORT Public Proxy ServersThis process is hyper-focused web browsing, but you don’t actually browse the web at all. ScrapeBox browses for you. In this way, it’s a bot or crawler software that really opens up the doors to your proxy automatic part of this is also what ScrapeBox is known for. Within the massive list of proxies, you can create individual or overall settings for the proxies, controlling the ping time, a number of threads used, when to rest or stop using a proxy. ScrapeBox will also automatically let you know when proxies are no longer functioning properly, saving you the headache of you’re a power proxy user, get ScrapeBox. It costs $197 retail, but there’s a continual code online to get it for $97. You can probably find a promo code on Black Hat World for even less. You pay once and it’s APIThe previous two methods should get you through most of your automatic proxy rotating needs. However, there are also some services that allow you to perform the same sort of actions within a website application interface (API) difference between a website API and a browser extension is that the website API is often a service you’re already paying for, not just a proxy switching method. IgerslikeA good example is IgersLike, an Instagram bot service. The entire process is done within the API of the IgersLike website—you log in and performs all your actions there, rather than having a piece of software installed on your the IgersLike example, there are countless ways to automatically rotate proxies, including many of the pinging and thread limits available in ScrapeBox. You’ll notice that IgersLike isn’t a service specifically for switching proxies, that’s just one of its wouldn’t register and use IgersLike just to rotate proxies, just like you wouldn’t buy ScrapeBox just to browse the internet with a different IP address. Each of these has a different level of user Ultimate Guide to Instagram Proxies for IG automationWhy Dedicated Proxies Are Necessary for Instagram AutomationProxy Provider APIThe other main way to automatically rotate your proxies with a web-based API is through your actual proxy provider. This will depend on the provider, of course. Just like IgersLike, you are paying your proxy provider for a specific service — in this case, it’s the actual proxies you’ll be using. When a provider says that it has a web-based API that you can control your proxies from, this is what they’re talking API of MPP proxiesLog into your proxy provider’s website and it will have a screen that shows all the proxies you paid for and what their status is. Some of these APIs will have specific functionality that will let you assign the proxies to different browsers, sites, or types of traffic. The best of these can be automated right there, so you don’t have to download software, an extension, or adjust your OS you want to know if a proxy provider has this functionality, shoot an email to customer Final ThoughtThe above methods will take care of all your proxy switching needs, and work best for the most common types of proxies: HTTP and HTTPS proxies, which are inherently web and browser-based. Each is really meant for the type of user you are, so identity that first, and then explore your options. I did want to mention another possibility. There are a number of proxy providers who sell rotating proxies, rather than assign you batches of single IP addresses. This is different from a proxy service that will change your proxies if they fail or if you request new ones. A rotating proxy service will typically refresh your proxies every couple hours, so you’ll receive new proxies multiple times a day. This is excellent for users concerned with bans and captchas, and those performing more complex functions like Ticketmaster spinning. In effect, this means you’ll never be using the same proxies, so they won’t ever bust.
