[squid-users] cache file format

[Xen]

I was assuming the files saved to the cache dir would just be plain 
files as they were fetched. Am I mistaken? It seems weird that when I 
run a 'file' on them, most of them are reported as "data" without 
discrimination.

I remember from Squid 3.5 on Windows that I could take a file and open 
it in an image viewer and high chance it would be a jpg or png. I am 
currently running 3.5.7 on Linux (self compiled).

Does Squid store extra data in the files in the header?.
