This will deny caching for anything with the string "asp" preceded by a
character. "wasp", "clasp", "3asp" and "#asp" are all examples of
strings that will match. Regular expressions have a number of special
characters (such as ".", "$" and "^"), which don't explicitly match the
ASCII characters they represent, unless escaped (usually with another
special character, "\").

This is probably what you were going for with the first line, but with
your current set up, it is redundant.

This is likely redundant. It will match "asp" at the end of the URL
path. Unless that is the full extent of the url_path (e.g.
http://www.example.com/asp), the first regular expression would match.

This is, again, redundant. Any string this would match would also be
matched by the first and second regular expressions.

If you use the mydomain acl defined above, and the ASP acl defined by
Luis Daniel Lucio Quiroz
(http://www.squid-cache.org/mail-archive/squid-users/200902/0351.html)
you would be set to not cache ASP pages from your domain on your Squid
server. Again, this will not prevent anyone else's server (or browser)
from caching the pages.
