htaccess Rewrite Rule for subdomain to page

Question

Currently I have a page residing at:

http://www.example.com/site/page

In my htaccess I have the current rule:

RewriteRule ^         


        

Answer 1

Try this one :

RewriteCond %{REQUEST_FILENAME} -f
RewriteCond %{REQUEST_FILENAME} -d
RewriteCond %{HTTP_HOST} ^(.*)\.example\.com$ [NC]
RewriteRule .* retailer.php?linklabel=%1 [L,QSA]

Answer 2

Try:

RewriteCond %{HTTP_HOST} !^www.[NC]
RewriteCond %{HTTP_HOST} ^(.+?)\.example.com$ [NC]
RewriteRule ^$ retailer.php?linklabel=%1 [L,QSA]

You can't match against the host in a RewriteRule, so you'll need to do it against the %{HTTP_HOST} var in a RewriteCond, then use the %1 backreference to get that match.

This will currently only match against URI's that are exactly /. So it won't match against http://page.example.com/something unless you change the regular express at from ^$ to ^something$.
