Redirecting non existing subdomains to root domains

[watsmyname]

Well

i have tried searching my problem but couldnt find, so i m posting it. I want to redirect non existing subdomain to the root domain. But if the subdomain exist then it goes to subdomain. like the subdomain http://mysub.mysite.com doesnot exist so if user enters this url in the browser i want to redirect them to http://www.mysite.com via htaccess. How can i achieve this??

 

Thanks

Currently non existing domain gets redirected to defaultwebpage.cgi.

If you only have a finite number of subdomains you could do this using mod_rewrite.

 

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_HOST} !^(www|mysub)\.mysite\.com
RewriteRule .* http://www.mysite.com%{REQUEST_URI} [R=301]
</IfModule>

Thanks a lot, but this doesnot work. Everytime i type http://mysub.mysite.com the page is redirected to 

http://mysub.mysite.com /cgi-sys/defaultwebpage.cgi

 

I dont know how to prevent to redirect to defaultwebpage.cgi. Couln't trace out it the code to redirect in httpd.conf file as well.

 

Thanks again

It worked after i added wildcard dns. in httpd.conf file.
