What is ProxyHandler and what is it for? (Android)
ProxyHandler is an app specifically from the Android system. This is an app designed for handling proxy configurations and integration with other apps. Usually, many android users look for information about the ProxyHandler app because they find it a little weird to have it installed without knowing what is it for.
During the course of this post, we will be explaining more in detail what is it for and how to deal with it during our daily android phone use. This is why we recommend on reading the whole material in order to not lose any tiny detail.
What is ProxyHandler for?
As we already explained before, the ProxyHandler is an app pretty well factory installed in the Android phones to manage not only the proxy configs but also the VPN settings of your WiFi connections.
Can I uninstall ProxyHandler?
The ProxyHandler app is very important only for the correct running of the VPN services but not important at all for the daily Android functioning. Normally, this app does not consume mobile data usage and is not going to be on the background unless you have it opened. This app only weighs around 50KB, so it is not going to be a problem to have it installed in our system.
If you want to uninstall the ProxyHandler android application, it would be the best just for safety security to first stop the application functions for a couple of days to see the behavior of your phone. If you see that it does not present any changes in the normal usage of your android phone, then you can uninstall it.
What permissions does this application have?
Permissions in Android are a complement of security systems that are always present in our system. At the time we install a certain application, access to certain resources on the phone can be whether or not required.
In this case, the ProxyHandler application does not require any permission to access to our phone.
ProxyHandler is a safe application or is it a virus?
The ProxyHandler is a safe application, but you got to keep in mind that some viruses may install themselves as a file with the same name. You have to make sure that you do not have some proxy running for your internet service. You can delete all the WiFi connections that you are not currently using. Unless you have a proxy set it up, it couldn´t be running either on the background. The only case of this application running is if an app is requesting it. in this case, I would recommend you to uninstall it.
In this article, you have learned almost everything about what is ProxyHandler and what is it for, also we explained some other situations that you may face with this app. If you have further questions about it, please let us know.
The proxyHandler Property (Sun Java System Application …
Sun Java System Application Server Enterprise Edition 8. 2 High Availability Administration GuideThe proxyHandler Property
The proxy handler for the Application Server is responsible for retrieving
information about the original client request that was intercepted by a proxy
server (in this case, a load balancer) and forwarded to the Application Server,
and for making this information available to the web application (deployed
on the Application Server) that is the target of the client request. If the
intercepting proxy server is SSL-terminating, the proxy handler retrieves
and makes available additional information about the original request, such
as whether the original request was an HTTPS request, and whether SSL client
authentication is enabled. Use the proxyHandler property
only if authPassThroughEnabled is set to true.
The proxy handler inspects incoming requests for the custom request
headers through which the proxy server conveys the information about the original
client request, and makes this information available to the web application
on the Application Server using standard ServletRequest APIs.
The proxy handler implementation is configurable, either globally at
the HTTP service level or for individual HTTP listeners, with the proxyHandler property, whose value specifies the fully-qualified class name
of an implementation of the abstract
class. Configurable proxy handler implementations allow the Application Server
to work with any proxy server, as long as the proxy handler implementation
knows about the HTTP request header names, and understands the format of their
values, through which the proxy server conveys information about the original
client request.
The proxy handler for the Application Server reads and parses the SSL certificate
chain from the request header. This allows a back-end application server instance
to retrieve information about the original client request that was intercepted
by an SSL-terminating proxy server (in this case, a load balancer). You can
use the default proxy handler settings, or configure your own using the proxyHandler property of the HTTP service or HTTP/HTTPS listener.
The proxyHandler property specifies the fully-qualified
class name of a custom implementation of the abstract class used by the listener or all listeners.
An implementation of this abstract class inspects a given request for
the custom request headers through which the proxy server communicates the
information about the original client request to the Application Server instance,
and returns that information to its caller. The default implementation reads
the client IP address from an HTTP request header named Proxy-ip,
the SSL key size from an HTTP request header named Proxy-keysize,
and the SSL client certificate chain from an HTTP request header named Proxy-auth-cert. The Proxy-auth-cert value must contain the
BASE-64 encoded client certificate chain without the BEGIN CERTIFICATE and
END CERTIFICATE boundaries and with \n replaced with% d% a.
You can only use this property if authPassThroughEnabled is
set to true. If you set the proxyHandler property on an
individual HTTP or HTTPS listener, it overrides the setting default setting
for all listeners.
Use the asadmin set command to set the proxyHandler property on the HTTP service or the individual HTTP listener.
To set the proxyHandler property on all HTTP/HTTPS
listeners, use the following command:
asadmin set
To set it on an individual listener, use the following command:
asadmin set
