Apache - Rewrite the subdomain to a location? - php

Question

I am sorry, I have tried for hours to get this working, but I haven't made progress...
I want to make it so that if a user on my site types user.site.com they will be taken to site.com/user, but the URL will still show user.site.com. How can I do this? With .htaccess? Server files?

Answer 1

Almost there Ken
RewriteEngine On
RewriteCond %{HTTP_HOST} !www.site.com$ [NC]
RewriteCond %{HTTP_HOST} ^([a-z0-9-_]+).site.com [NC]
RewriteRule (.*) %1/$1 [QSA,L]
%1 = what's before .site.com
$1 = what you got after the /
If you have test.site.com/foo.php , you would have /test/foo.php.
if you just want test, just forget about the $1.
QSA = query string append,
L = Last.
You should read the url about mod_rewrite in #phihag post.

Answer 2

Use mod_rewrite:
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} !www.site.com$ [NC]
RewriteCond %{HTTP_HOST} ^([a-z0-9-_]+).site.com [NC]
RewriteRule (.*) %1/$1 [QSA,L]
If you want to link to resources, either use full (http://site.com/user/static/x.css) or relative (static/x.css) URLs. Absolute URLs (/user/static/x.css) will need to be crafted differently when this rule is in effect.

To keep the original address in the address bar you will need a reverse proxy rather than a redirect. Redirecting tells the browser to send a second request to the server with a different address, reverse proxy tells the server to find another page and send it without notifying the browser about it (this is what you want I believe). Reverse proxy is achieved with the [P] flag in mod_rewite
Make sure mod_rewrite, mod_proxy and mod_proxy_http are loaded and put the directives
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
RewriteEngine on
RewriteRule ^/(.*) http://site.com/user/$1 [PL]
into your virtual host configuration for user.site.com or .htaccess if you do not have root privileges. This will proxy all pages from the subdomain to the main domain folder. If you only want to proxy the index page use RewriteRule ^/ http://site.com/user instead.
I assume you are using http and not https. If so, it gets a little more complex...
