We have just transferred over to Nginx, and so far we love the stability, and the speed it offers over Apache. However, with Apache we had the ability to have "username.domain,com" setup in our re-writes, which pointed to "file.php?id=username", however I cannot figure out a way to do this similar in nginx.

Could someone help us out.

Cheers,

Jacob

Something like this might work:
[code]
if ($host ~* (.*)\.domain\.com) {
$user = $1;
rewrite ^(.*)$ http://domain.com/file.php?=$user permanent;
}
[/code]

Note that this will not work for www.user.domain.com, although you can add that easily enough. Likewise, without a qualifier, it'll also consider www.domain.com a user and forward accordingly.

That's missing the word 'set' before then $user declaration line, btw (too late to edit the post).
