Wildcard Sub Domain Path Issues

Question

I have an htaccess rewrite for wildcard sub domains which rewrites foo.domain.com to domain.com/index.php?id=foo. This is done using:

RewriteCond %{HTTP_HOST} !^www\.domain\.com [NC]
RewriteCond %{HTTP_HOST} ^((www\.)?([a-z]+)\.)domain\.com [NC]
RewriteRule .? index.php?id=%3 [L]

This works OK, but all content on the site is referenced to the root e.g:

 "/content/imgs/logo.jpg" or "/ajax/upload.php"

The wild-card sub domain changes the root and all content is referenced to:

"http://foo.domain.com/content/imgs/logo.jpg"

And the content cannot be found because it is not located on this subdomain.

I know you can use the html < base > tags to place a prefix on all href locations but this does not help in javascript for ajax requests.

Is there anything that can be done in htaccess to solve this problem?

Thank you.

I think I may have the solution to your problem Christopher!

Your rewrite condition was being applied to ALL included content such ass css/js/images etc. Which mean it was trying to rewrite this content to index.php?id=%3 instead of style.css.

By adding the line RewriteCond %{REQUEST_FILENAME} !-f above the condition and placing the entire condition at the bottom of the htaccess means that it will only apply to files/directories that DO NOT EXIST (i.e. only to wildcard subdomains).

Try the following:

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{HTTP_HOST} !^www\.domain\.com [NC]
RewriteCond %{HTTP_HOST} ^((www\.)?([a-z]+)\.)domain\.com [NC]
RewriteRule ^(.*)$ "http://domain.com/index.php?id=%3" [L,P]

Hope this helps you mate!
