in reply to A check on whether pages on a web site have changed
LWP::Simple contains a "mirror" function that does something similar. The description says:
mirror($url, $file)
Get and store a document identified by a URL, using If-modified-since, and checking the Content-Length. Returns the HTTP response code.
You could either use that function or use the code as a basis for your own program.
