.htaccess subdomain redirect problem

[TechMan]

Hi,

I have a website let's say www.webmasterworld.com

And I have a subdomain something.webmasterworld.com

Both main domain and sub domain are pointing to directory "public_html"

I have .htaccess on root which redirects any URL without www to www. For e.g. if user enters webmasterworld.com then he will be redirected to www.webmasterworld.com If user enters webmasterworld.com/mypage.htm then he will be redirected to www.webmasterworld.com/mypage.htm

Now the problem is this is also affecting my subdomain. Because if someone enters something.webmasterworld.com/visit.htm then he is redirect to www.webmasterworld.com/visit.htm

I don't want this! If user enters subdomain then I don't want to redirected to www domain. This is what I have in my .htacces file

RewriteCond %{HTTP_HOST} !^www.webmasterworld.com$ [NC]

RewriteRule ^(.*)$ [webmasterworld.com...]

[R=301,L]

Can you please tell me what should I do to solve above problem?

Thanks

RewriteCond %{HTTP_HOST} !^((sub|www)\.example\.com)?$ [NC]

Don't forget to escape literal periods in RegEx patterns.

Thanks man!

There is apparently a formatting problem with the code, or with the code as posted here. Also, the use of [NC] in the RewriteCond is not advisable, since the apparent goal is to fully-canonicalize these subdomains. In the interest of clarity, the correctly-formatted solution would be:

RewriteCond %{HTTP_HOST} !^((sub|www)\.example\.com)?$
RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]

Yes, the [NC] was a typo. Remove it.
