fascinating but strange server response!
Yef
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.

But I've found that the URL works when I remove these
'characters'. Which incidentally, 3 hex digits is the wrong
number for either 1 or 2 characters. Also note, in one case
I found that these 3 character were within the http:// expression.
Clearly these characters are supposed to be ignored.
But when did this become a standard that browsers adhere to?
It seems to be an attempt at preventing spidering.

It looks like you've seen "chunked content transfer encoding";
see RFC 2616, chapter 3.6.1.
