How to route Apache ProxyPass configuration through another proxy server? (Proxy to proxy)

Sometimes we do configure forward proxy (ex: Squid Proxy) behind Apache server. This page help us to understand how to configure ProxyPass configurations within Apache httpd.conf file.

Incase if we want to route our requests through proxy from within Apache, then you need to add ProxyRemote under your VirtualHost configurations as shown below:

    SSLEngine on
       [cert file config]
    ProxyRemote *
    ProxyPass /myapp/

As per the Apache documentation, ProxyRemote defines remote proxies to this proxy. The syntax is:

ProxyRemote match remote-server

match is either the name of a URL-scheme that the remote server supports, or a partial URL for which the remote server should be used, or * to indicate the server should be contacted for all requests. remote-server is a partial URL for the remote server.

Here is some examples:

ProxyRemote "" ""

ProxyRemote "*" "http://cleverproxy.localdomain"

ProxyRemote "ftp" "http://ftpproxy.mydomain:8080"

doPost Vs doGet methods
doGet() method is used to get information, while doPost() method is used for posting information. doGet() requests can't send large amount of information and is limited to 240-255 characters. However, doPost()requests passes all of its data, of unlimited length. A doGet() request is appended to the request URL in a query string and this allows the exchange is visible to the client, whereas a doPost() request passes directly over the socket connection as part of its HTTP request body and the exchange are invisible to the client.
