Hi all,

Recently, I fetched a page from a server, its info is:

Server: Apache/1.3.33 (Unix) mod_fastcgi/2.4.2 PHP/4.3.10
mod_ssl/2.8.22 OpenSSL/0.9.7d
X-Powered-By: PHP/4.3.10

Within the HTML response I found numerous lines that had only
3 characters each, always 0..9 and a..f i.e. hexadecimal.

These were always inside of links.

Can someone tell me what these little buggers are all about?

Thanks.
