I assume we are talking about the url_regex acl type here?

? and $ is special regex characters.
  ^ matches the beginning
  $ matches the end

Examples illustrating their use in url_regex:

  ^http://
  \.gif$

Similarily for the domain_regex:

  ^www\.*\.com$ matches www.<anything>.com
  ^www\. matches www.<anything>

Without these magic characters the above matches would match if the sequence
if characters is found anywhere in the URL (or domain). Example

url_regex \.gif
will in addition to .gif files also match
   http://www.giffel.com/
   http://www.example.com/abc.giffy/contact.html
