Pass subdomain as parameter

[jimmyh Profile]

I'm new to ISAPI_Rewrite & regular expressions. I'm in need of a rewrite rule that will remove the subdomain and pass it as a parameter. For example:

mysubdomain.mydomain.com

should become

mydomain.com/Landing.aspx?ID=mysubdomain

Any help would be appreciated.


Note: I'm using the full version of ISAPI_Rewrite so this rule will be at the site-level.

Hello,

Try using the following:

Code: Select all

RewriteEngine on
RewriteBase /

RewriteCond %{HTTP:Host} !^www\.mydomain\.com$
RewriteCond %{HTTP:Host} ^([^.]+)\.mydomain\.com$
RewriteRule ^$ /Landing.aspx?ID=%1 [NC,L]

You did not specify if you want a 301-redirect or a rewrite,so in case you want it to be redirect, use [NC,R=301,L] instead of [NC,L].
