Url重写域名[关闭]

Ok so i have hosting with godaddy and i have 2 websites hosted with them. I make a htaccess rule and add it into my main dir and it effect both domain names. Im just wondering if there anything i can add to it to only work for the one domain name ?? My mod rewrite rule is has follwed

Options +FollowSymLinks
RewriteEngine on
RewriteRule (.*)_ index.php?pageid=$1

When i add this to my main dir it effect both websites i have hosted. The rule ment to be changing this mysite.com?index.php to this mysite.com/index_

But has i have said i need to some how set a domain name in side it some how.

Add this line before your RewriteRule

RewriteCond %{HTTP_HOST} ^www.mydomainname.com$

Your rule will affect only this domain, your .htaccess should look like this :

Options +FollowSymLinks
RewriteEngine on
RewriteBase /
RewriteCond %{HTTP_HOST} ^www.mysite.com$
RewriteRule (.*) /index.php?pageid=$1

This would match

http://www.mysite.com/week1

and rewrite it to

http://www.mysite.com/index.php?pageid=week1

Then you can access $_GET['pageid'] to get the value
