[squid-users] light weight ICAP server that isn't dead :o)

[Luis Miguel Silva]

Thanks Amos.

Well, that's exactly what I'm going to need to develop too (the plugin
part), I just found it weird that the C-ICAP service was still version
0.3.5, even though it was really old. If it is mature, I would expect it to
get to v1.0 and cease development :o)

So...what one would you recommend if you wanted to easily create
(lightweight) custom filtering capabilities?
I'm very inclined to adopt c-icap. Thoughts?

Thanks,
Luis
