ProxyHTML to rewrite URL
Ok, this is what I ended up doing to get it working
ProxyPass /translate/ http://www.example.com:8077/ProxyPassReverse /translate/ http://www.example.com:8077/ProxyHTMLURLMap http://www.example.com:8087 /translate/<Location /translate/> ProxyPassReverse / SetOutputFilter proxy-html ProxyHTMLURLMap http://www.example.com:8077 /translate/ ProxyHTMLURLMap / /translate/ ProxyHTMLURLMap /translate/ /translate/ RequestHeader unset Accept-Encoding</Location>This seems to work well. The ProxyHTMLURLMap http://www.example.com:8077 /translate/ line was only needed to translate some "referrer" based urls that caused some pages to end up trying to serve directly from the 8077 port server.
