Ok, This is what I am trying to do

I have a path:

http://localhost/profile.cfm?id=4539872

I want to be able to hit the URL using the following path (or any
other 8 digit userID):

http://localhost/4539872

Here is my mod rewrite rule:

      Options +FollowSymLinks 
      AllowOverride None 
      RewriteEngine On
      RewriteBase /
      RewriteRule ([0-9]+) profile.cfm?id=$1 [QSA,L] 

The above rule works, but all the images will not load on the pages.
If I add a directory in front, the rule works AND images load. Like
this:

RewriteRule /somedirectory/([0-9]+) profile.cfm?id=$1 [QSA,L]


How do I modify this rule so I do not have to add a fake extra directory in
the path I dont need to get the site images to load?

Try adding "^" and "$" around the first regular expression, like so:

RewriteRule ^([0-9]+)$ profile.cfm?id=$1 [QSA,L]

Those are anchors that match the beginning and ending of the string, respectively.

Ok, I had a feeling it was something like that.

So, if I wanted to allow alpha characters and numeric mixed combos
from the same path, I would do:

RewriteRule ^([0-9a-zA-Z]+)$ profile.cfm?id=$1 [QSA,L]

correct?

Yeah, that ought to do it.

Thanks vladimir. Post an answer comment so I can process.
