Yes. The URLs in question don't provide a Last-modified: header. localhost junk # wget --server-response http://www.pitpass.com/forum/viewforum.php | head -n 40 --15:10:58-- http://www.pitpass.com/forum/viewforum.php => `viewforum.php' Resolving www.pitpass.com... 64.62.155.120 Connecting to www.pitpass.com|64.62.155.120|:80... connected.

I believe that if Last-modified is not provided, you can safely assume that the page is dynamic, or should be treated as such -- I.e., the page will be different every time you view it, in theory. Unless you are pounding the same page more than once per second, you could probably just store time() as the Last-modified in that case, and move on with life. Or you could leave it as 0 and know that that means that the page had no Last-modified header. -- Some people have a "gift" link here. Know what I want?
