I'm trying to configure Apache on Centos 6 to proxy and reverse proxy traffic to an http server of a third party provider.

The setup should work like this: https://mydomain.com/proxy/ proxies all trafic transparently to http://thirdparty.com/app/

The issue I'm having is any request made to https://mydomain.com/proxy/ gets a 301 redirect in response.

These are all of the proxy related options in my VirtualHost

SetOutputFilter proxy-html
ProxyHTMLExtended On
ProxyRequests Off
SSLProxyEngine On

<Proxy *>
Order deny,allow
Allow from all
</Proxy>


ProxyPass /proxy/ http://thirdparty.com/app/
<Location /proxy/>
        ProxyPassReverse /
        ProxyHTMLEnable On
        ProxyHTMLURLMap http://thirdparty.com/app/ /proxy/
        ProxyHTMLURLMap / /proxy/
</Location>

We have a similar setup and are using this (of course you need to load before mod_proxy, mod_ssl and mod_proy_http):

ProxyRequests Off
# SSLProxyEngine On # only required if the proxied service would be HTTPS as well
                    # Meaning if we would reverse proxy https://thirdparty.com/app/
                    # Thanks @Piskvor for the clarification.

<Proxy *>
  Order deny,allow
  Allow from all
</Proxy>


ProxyPass /proxy/ http://thirdparty.com/app/
ProxyPassReverse /proxy/ http://thirdparty.com/app/
<Location /proxy/>
  ProxyPassReverse /
  Order deny,allow
  Allow from all     
</Location>
Header edit Location ^http://thirdparty.com/app/ https://thirdparty.com/app/

  • I found one bug in that I was using thirdparty.com which redirects to thirdparty.com. However my original configuration did not work with this either, yours did. Thanks.

    Note that SSLProxyEngine is not necessary here - that would be needed if you proxied to httpS://thirdparty.com/

    @Piskvor indeed after checking the documentation again, it is not necessary in that case. I will update the answer. Thank you for pointing that out.
