[users@httpd] Problem with wildcard subdomains and ProxyPass

Hi,

I want to use Apache to proxy requests like domain.tld.MyDomain.tld to
domain.tld.

I've tried this :

<VirtualHost *:80>
      RewriteEngine on
      RewriteCond     %{HTTP_HOST}    (.*).MyDomain.tld$
      RewriteRule     (.*).MyDomain.tld$  $1
      ProxyPassMatch /http://$1/
</VirtualHost>

But of course it doesn't work.
I've tried many other solutions, but no one works.

Do you have an idea of the manner to resolve my problem ?

Thanks by advance,

Thibaut

Thank you Tom, it's the manner we found and will use.

Have a good day,

Oh, I see what you are trying to do now. You want to request
'facebook.com.mysite.com' and have apache proxy to 'facebook.com'.

It would probably be easier to set up a real http proxy server and use
that instead, almost certainly this approach will fail at some point.
However - untested, but something like this should suffice:

     RewriteEngine on
     RewriteLog logs/rewrite.log
     RewriteLogLevel 5
     RewriteCond     %{HTTP_HOST}    (.*).MyDomain.tld$
     RewriteRule     (.*)  %1$1 [P]


If it doesn't work, there will be some lovely debug information in
logs/rewrite.log (relative to server root).

Cheers

Tom

Yes, it's what I want to do. Isn't it the good way ?

If you have a matching group in a RewriteCond, the match is available
in %N, not $N.

Capture in RewriteCond => %N
Capture in RewriteRule => $N

However, you can't use rewrite and mod_proxy like that. What you can
do is to use RewriteRule/Cond to generate a URL, and ask apache to
proxy to that URL by giving the RewriteRule a [P] flag (ie, no
ProxyPassMatch).

I'm still not sure what you are trying to do though.
Do you mean proxy - you want to connect to a different server, fetch
that content over the network to this server, and then deliver it to
the client?
Or do you want an internal rewrite - ask apache to internally request
this content from a different vhost hosted by this apache server?

Cheers

Tom
