Rewrite Help

[kau]

I need some help with mod_rewrite.

I have setup a subdomain that uses member.php

subdomain.domain.com/member.php

I want to set it up so

subdomain.domain.com/Username/

Will go to;

subdomain.domain.com/member.php?username=Username

However they will never know the member.php path. It just stays at subdomain.domain.com/Username/

I can do this using;

RewriteCond %{REQUEST_URI} ^(.*)/
RewriteRule ^([^/]*)/$ member.php?username=$1

However this presents some issues. If you hit
subdomain.domain.com/Username it errors out.

I've tried some code to add the trailing slash but it gets confused when a user name has a . in it.

Any help would be appreciated.
