. in a regexp is "any character".
* is 0 or more repetitions of the preceding regex "character".

A correct url_regex pattern matching what you appears to be trying to
match is something like

^http://[^.]*\.[^.]*chat

Explanation
^ = Beginning of line
http:// = the string literal "http://"
[^.]* = 0 or more of any characters except .
\. = .
[^.]* = 0 or more of any characters except .
chat = the string literal "chat"

This would match

http://www.chatline.com/
or
http://www.nochatter.net/
but not
http://chat.example.com/

A regexp matching the string "chat" anywhere in the host name would be

^http://[^/]*chat

or even simpler
acl chat dstdom_regex chat
