How can I use a reverse proxy to modify a query string parameter in an HTTP response header coming from my backend server?
I'm setting up Apache 2.2 as a reverse proxy in front of a 3rd party app. I have just about everything working except for the following. If I hit the URL:
http://myreverseproxy.server.com/some_path/some_page?query_string_params
... the reverse proxy passes this on to the backend server, which generates a response header with a location like:
http://3rdparty.server.com/another_path/another_page?p_submit=http%3A%2F%2F3rdparty.server.com%2Fyetanotherpath
Using ProxyPassReverse, I can change the first bit of the URI as needed, but how can I rewrite the query string parameter p_submit (from "3rdparty.server.com" to "myreverseproxy.server.com"? Will ProxyPassReverse allow me to alter parameters? Or, should I be using mod_rewrite (RewriteRule)?
Any guidance is appreciated.
Thanks,
Brian
