Question

Having spent the past few hours looking for a solution, I thought I’d ask here.

I’m looking for a way to process links such as:

http://subdomain.domain.com/page/subpage/

so they are passed to the server as:

http://domain.com/index.php?subdomain=subdomain&page=page&subpage=subpage

which can be taken by index.php to display the correct page information.

I can get the page and subpage to work but have no clue how to get the subdomain. Note: if there is no subdomain, I would like that field to either be left blank or contain a default value.

Any assistance would be much appreciated. 🙂

Edit:
Just to clarify, I want the first URL to be what the user sees and can input into the address bar and the second URL to be the page that is loaded by the server when the user navigates to the first URL.

My .htaccess file

Options +FollowSymlinks -MultiViews -Indexes

RewriteEngine On
RewriteBase /

# Remove 'www'
RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
RewriteRule ^(.*)$ http://%1/$1 [R=301,L]

# Add slashes
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !index.php
RewriteCond %{REQUEST_URI} !(.*)/$
RewriteRule ^(.*)$ http://resolutiongaming.com/$1/ [L,R=301]

# Subdomain redirect
RewriteCond %{HTTP_HOST} ^resolutiongaming.com$
RewriteRule ^webdev/$ http://webdev.resolutiongaming.com [R=301,L]
RewriteRule ^artwork/$ http://artwork.resolutiongaming.com [R=301,L]
RewriteRule ^music/$ http://music.resolutiongaming.com [R=301,L]

You may try this in one .htacces file in root directory:

Options +FollowSymlinks -MultiViews
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST}  ^(?:www\.)?([^\.]+)\.domain\.com
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI}  ^/([^/]+)/([^/]+)/?   [NC]
RewriteRule .*     http://domain.com/index.php?subdomain=%1&page=%2&subpage=%3  [R=301,L]

It will redirect permanently:

http://subdomain.domain.com/page/subpage/ or http://www.subdomain.domain.com/page/subpage/

To:

http://domain.com/index.php?subdomain=subdomain&page=page&subpage=subpage

For the rule to work, the incoming URL scheme: /page/subpage/ must be kept.

To replace permanent redirection with silent mapping, remove R=301 from [R=301,L] or replace it with R for temporal redirection.
