使用htaccess将所有流量从根重定向到特定的子域页面

Question

I have a site that has been up for some time. I had a blog on a subdomain for some time. I have decided to do away with the main site and just support the blog subdomain.

I have a redirect setup for this, but it carries all the extra parameters through to the blog which results in a file not found page appearing. I just want the redirect to go to the index page without parameters.

What I currently have in my .htaccess file is this

RewriteCond %{HTTP_HOST} ^.*$
RewriteRule ^/?(.*)$ "http\:\/\/blog\.foo\.org\/index\.php" [R=301,L]

When I get a request to

http://www.foo.org/foo/foo/?module=foo

it redirects to

http://blog.foo.org/foo/foo/index.php?module=foo

I want it to redirect to http://blog.foo.org/index.php

Answer 1

You have to specify the query in the replacement to override the original:

RewriteCond %{HTTP_HOST} !^blog\.example\.org$ [NC]
RewriteRule ^ http://blog.example.org/index.php? [R=301,L]

Answer 2

RewriteEngine On
Options +FollowSymlinks
RewriteCond %{HTTP_HOST} ^(www\.)?foo\.org$ [NC]
RewriteRule ^ http://blog.foo.org/ [R=301,L]
