htaccess rewrite sudomain to variable

[Achilles08]

Hello,

i have a site with php application which writes/uses subdomain to a variable. I have tried couple of rules but nothing worked out. here is htaccess code


Options +FollowSymLinks

RewriteEngine on

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f

RewriteBase /appfolder/
RewriteCond %{HTTP_HOST} !www.site.com:8888$ [NC]
RewriteCond %{HTTP_HOST} ^(www.)?([a-z0-9-]+).site.com:8888 [NC]
RewriteRule (.*) /index.php?var1=home&var2=start&var3=%2 [NC,QSA]

here i want to grab subdomain value to var=3...please help

Thanks in advance

Your first two RewriteConds have no associated RewriteRule.

Escape all the literal periods (. becomes \.) in the patterns, othersise your pattern is ambiguous.

The code must be placed in the internal server locations that all the subdomains resolve to and you'll also need to have altered the DNS settings to allow wildcard subdomains.

Add the [L] flag to the rule.
