Custom module menu path renaming/redirection

Question

Is it possible to create path like subdomain for custom module menu?

For example create url like xyz.example.com if path is example.com/xyz where xyz is custom module menu.

I've already tried to use .htaccess file

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

It correctly changing url from example.com/xyz to xyz.example.com but xyz.example.com redirected me to HOME page of the site.

I just want to change the url from example.com/xyz to xyz.example.com where module result will be displayed.

Thanks.

EDIT : My requirement is similar to this

Answer 1

You could modify $_GET['q'] during hook_boot(), something like the following.

function mymodule_boot() {
  $_GET['q'] = implode('.', array_slice(explode('.',$_SERVER['HTTP_HOST']), 0, -2));
}

There is probably a regex that could do the same as that explode/implode mess, but that does the trick to start with.

Answer 2

$1 will be example.com/... not the module path that you want.

Specify the path as per:

RewriteCond %{HTTP_HOST} ^(www\.)?example\.com$
RewriteRule ^ mymenupath [R,L]

Where you say the menu (mymenupath) is set up in your custom module.

Log the rewrites in your apache config to verify where the redirects are going:

LogLevel alert rewrite:trace3
