Subdomain faking with mod_rewrite?

[AJRAD]

Hi,
Can somebody help me with this please:
I'm creating a site where users register and get a subdomain.. but I don't want the subdomains to physically exist - I want to use htaccess to... ahhh I'll demonstrate:

I want

http://user1.domain.com/anything.php

to go to

http://www.domain.com/anything.php?user=user1

http://user2.domain.com/anything.php

==>

http://www.domain.com/anything.php?user=user2

etc etc

I do *NOT* want the page to redirect.. I want user.domain.com/anything to display in the address bar but use the other file.

Thanks in advance.
-Alex

If you are not going to use sub-domains then this is not an apache issue.

I am using mod_rewrite - it is an apache issue.
How do I do what I said?

I tried this out, it seems to work. You will have to enable mod_proxy:

No.. nothing on that page works.
What is mod_proxy and how do I enable it?

By the way.. my host has enabled wildcard subdomains and everything should work but something is wrong.

You need to install mod_proxy, either built in or dso. and mod_rewrite of course:

LoadModule proxy_module libexec/libproxy.so
...
AddModule mod_proxy.c

Also enable the rewrite logs and level to see what is happening:
RewriteLogLevel 2
RewriteLog /usr/local/apache/logs/rewrite_log


I was testing on a local box, where
this was the default VirtualHost:

<VirtualHost *:8080>
ServerName 127.0.0.1
DocumentRoot /usr/local/apache/htdocs
RewriteEngine on
RewriteCond %{HTTP_HOST} ([^.+])\.domain\.com [NC]
RewriteRule ^(.*)

http://www.domain.com:8080/anything.php?user=%1

[P]
</VirtualHost>
