Hi, I was presented with the seemingly straightforward task of converting URLs such as: http://cellularmanagerpp.aliant.net/myProg?param1=val1&url=http://cellularmanagerpp.aliant.net¶m3=val3 to: http://erie:9090/myProg?param1=val1&url=http://erie:9090¶m3=val3 Attempt 1 --------------- Use a reverse proxy to forward the request to erie:9090 and use mod_rewrite to change the value of the "url" query parameter. ####################### httpd.conf ####################### RewriteEngine on # This changes the 'url' query param RewriteCond %{QUERY_STRING} ^(.*)url=http%3A%2F%2Fcellularmanagerpp%2Ealiant%2Enet(.*)$ RewriteRule ^(.*)$ $1?%1url=http\%3A\%2F\%2Ferie\%3A9090%2 [P] ProxyRequests Off <Proxy *> Order deny,allow Allow from all </Proxy> # This should redirect the request to erie:9090 ProxyPass / http://erie:9090 ProxyPassReverse / http://erie:9090/ ####################################################### The re-writing appeared to work fine, but it seemed the rewritten URLs weren't being sent to the proxy. Attempt 2 --------------- Use mod_rewrite to change the entire URL (i.e. not just the parameter value), and a reverse proxy to change the hostname in the response ####################### httpd.conf ####################### RewriteEngine on # This changes the 'url' query param RewriteCond %{QUERY_STRING} ^(.*)url=http%3A%2F%2Fcellularmanagerpp%2Ealiant%2Enet(.*)$ RewriteRule ^(.*)$ $1?%1url=http\%3A\%2F\%2Ferie\%3A9090%2 [NE] # This changes the hostname RewriteRule ^/(.*)$ http://erie:9090/$1 [P,QSA,L] ProxyRequests Off <Proxy *> Order deny,allow Allow from all </Proxy> # This makes the response look like it came from Apache, rather than erie:9090 ProxyPassReverse / http://erie:9090/ ####################################################### This appears to work. However, because I'm using mod_rewrite, only the request line is changed. For example, the value of the "referrer" header still references "cellularmanagerpp.aliant.net". Anyway, my questions are these: - Why didn't the proxying work with the rewritten URLs in Attempt 1? - Is there a way to achieve my goal which also rewrites the headers? - In httpd.conf it possible to set a variable whose value is "erie", then reference this variable, so that I don't have to repeat "erie" in multiple places?
