[SOLVED] How to Ignore URL Path in sub domain

[tqla]

Hello. I have a subdomain called

sub.mydomain.com

When I type that in my address bar I get taken to

www.mydomain.com/sub

Perfect. Here's the issue. When I type

sub.mydomain.com/test

the server looks for "test" and gives me an error 404. I know the server is doing the right thing but I want it to not treat "/test" like a directory but instead append the word test to

www.mydomain.com/sub

like this:

www.mydomain.com/sub/test

Is this possible? Thanks.

 

Or better yet, is it possible to configure the server to ignore the path altogether and just resolve to

www.mydomain.com/sub

with the word "test" still in the URL so that I can parse the URL out and get the word test and make it a variable.

update. .htaccess is what I need to do this so I'm clicking solved. (even though I'm not sure how to do it yet)
