重定向子域的根目录，而不是文件夹

Question

Probably a simple .htaccess RewriteRule problem but I can't figure it out.

This is the situation:

• subdomain.domain.com now has a simple HTML page
• subdomain.domain.com/folderA , subdomain.domain.com/folderB contains app logic, app data, ...

I'm going to upgrade the simple HTML-page, but in a CMS so it can't stay on that location anymore.

How do I redirect all traffic going to subdomain.domain.com ( /index.htm or any other file here) to www.domain.com/somepage without rewriting requests to subdomain.domain.com/folderA etc or avoiding that requests made to any of those files end up at www.domain.com/folderA/ ...

Answer 1

Try the following in the .htaccess file in the document root of your subdomain:

RewriteEngine On
RewriteCond ${REQUEST_FILENAME} !-d
RewriteRule ^[^/]+$ /somepage [R=302,L]

For any URL that does not contain a slash (directory separator) and is not itself a directory then redirect to /somepage .

This does assume that you have DirectoryIndex set appropriately so that a request for the bare domain is rewritten (which is not handled by the above).

Change the 302 (temporary) redirect to 301 (permanent) when you are sure it's working OK. (301s are cached.)
