URL Rewriting Problem

Question

I'm trying to rewrite my URL's subdomain.

http://username.domain.com will show content of http://www.domain.com/user.php?u=username but URL stay as http://username.domain.com . (I mean url masking)

(Username's can contain a-z 0-9 and hypens) Also if subdomain is www or api, don't redirect them

I'm using this for my .htaccess

RewriteEngine on
RewriteCond %{REQUEST_URI} !^/index\.php$
RewriteCond %{HTTP_HOST} !^www\.domain\.com
RewriteCond %{HTTP_HOST} ^([^.]+)\.domain\.com
RewriteRule .* /user.php?u=%1 [L]

(After @mfarver's advice) I'm trying this

RewriteEngine on
RewriteRule .* /user.php?u=%1 [L]

but this time getting 500 Internal Server error:

[Mon May 30 20:10:44 2011] [alert] [client 81.6.xx.xxx] /home/blablabla/public_html/.htaccess: AllowOverride not allowed here

(from error log)

My server's httpd.conf file's virtualhost settings

<VirtualHost 109.73.70.169:80>
    <IfModule mod_userdir.c>
        UserDir disabled

    # To customize this VirtualHost use an include file at the following location
    # Include "/usr/local/apache/conf/userdata/std/2/USERNAME/DOMAIN.net/*.conf"

</VirtualHost>

Also *.DOMAIN.net added to my DNS ZONES as A record.

Looks good but debugging mod_rewrite is always tricky. I would recommend breaking it down. Comment out all of the conditions and make sure the rule works first, then add them back one at a time. In my experience mod_rewrite behaves slightly different in .htaccess vs in the conf files. Also make sure that you are actually using .htaccess (ie overrides are allowed) — mfarver, May 30 '11 at 18:05
I'm sure server using .htaccess file. Because when i type random characters to my .htaccess file, i'm getting 500 INTERNET SERVER error. So my .htaccess file is working. I'm not similar with .htaccess commands very well. First i will comment out 2nd 3th and 4th lines right? — Eray, May 30 '11 at 18:30
@mfarver, after your advice i'm delete conditions but this time i'm getting error. Please look ADDITION 1 on answer. I was edited it. — Eray, May 30 '11 at 18:35
You probably forgot to restart httpd after editing httpd.conf — Alvin Wong, Sep 02 '12 at 03:48
AllowOverride not allowed here: says what the problem is. Totally unrelated to the rewrite. That user is using a directive in .htaccess that isn't allowed (think about it, if you'd allow AllowOverride in .htacces, then it has zero use for server and vhost level and the webserver admin looses control). — , Jan 22 '14 at 23:50

If you are using a .htaccess file, your server should have AllowOverride direction for these domain contexts. Check you servers general configuration.

Also you need a redirect for thise kind of rewriting.

instead of: RewriteRule .* /user.php?u=%1 [L]

use: RewriteRule .* http://www.domain.com/user.php?u=%1 [r,L]

After your edit: you do not need redirecting.

After chatting over this problem on another platform I have concluded this problem is not only about rewriting. Domain names and vhost configuration are not set properly. – fsniper May 30 '11 at 20:50

This should do the job - you need "PT" to stop it from being a redirect. If it isn't a redirect the URL won't change in the browser:

RewriteEngine on
RewriteCond %{REQUEST_URI} !^/index\.php$
RewriteCond %{HTTP_HOST} !^www\.domain\.com
RewriteCond %{HTTP_HOST} ^([^.]+)\.domain\.com
RewriteRule .* /user.php?u=%1 [PT,L]
