URL going into infinite loop when using proxypass and rewriterule

[krish1]

Hi Everyone

I have a requirement where i need to make this URL

www.example.com/test1/test2/* look like
www.example.com/a/b/* in the address bar

For this i am writing this code in the config file,

ProxyPass /a/b/* www.example.com/test1/test2/*
ProxyPassReverse /a/b/* www.example.com/test1/test2/*

RewriteEngine on
RewriteRule ^/test1/test2/(.*) www.example.com/a1/a2/$1 [R,L]

after doing this, when i hit this url
www.example.com/test1/test2/* its getting converted to
www.example.com/a/b/* in the address bar, but

i am getting this message

server is redirecting the request for this address in a way that will never complete


Thanks in Advance

You have an infinite redirect loop.

Use the Live HTTP Headers extension for Firefox to examine the server response.

It's doing exactly what you told it to do. The ProxyPass rule says "when asked for /a/b/ show /test1/test2/" and the RewriteRule says "when asked for /test1/test2/ show /a/b/". It's like telling a robot to take a shovel and dig a hole. It will dig to China because you haven't told it when to stop digging.

Most but not all infinite loops can be stopped by a RewriteCond that looks at {THE_REQUEST}.

Is your error message coming from the server or the browser? In general, servers deal with internal-redirect errors while only browsers can stop external-redirect errors. But a Proxy is neither fish nor fowl.

Do you really want a temporary redirect? R alone defaults to 302, but you almost always want R=301.

Similarly, do you really need a Proxy at all? I kinda suspect you only need a Rewrite.
