HTTP Anti-Virus Proxy

Another minor issue thats been brought to my attention is with certain sites not working through HAVP. One such site is https://www.buxfer.com/blog/
Using IE pointing at the HAVP proxie it returns an Invalid Request page off the proxie it renders fine. Oddly enough the same page on Firefox through HAVP returns fine.
I dug a bit deeper and found in the havp.log these entries
03/01/2007 15:09:28 (172.18.4.221) Invalid request from browser

I assume you have compiled SSL tunneling support in HAVP?

What IE version specifically?

Assume I haven't (since I just did the basic ./configure make make install) how do I compile it with SSL?

IE7 specifically.

Why do you even want to have SSL proxy support? So clients cannot directly connect to outside world? Better solution would be to have Squid as generic proxy.

From configure --help:

--enable-ssl-tunnel Enable SSL proxying (not scanned, only forwarded!)

Not sure why I would or would not want SSL Proxy support.. I Just want a proxy that scans for virus on web traffic to stop it before it enters the network. The sites the company scrapes cover a wide variety and quite a few have some not so nice content. This paticular blog has SSL for some odd reason. And as for enabling or disabling things on configure, I just read the install file and do a basic install unless I fully understand added features. But anyways I enabled the ssl_tunnel and the site works through proxy. I assume this means that all ssl sites won't be scanned for virus but this is a fair trade off.. few sites are SSL and those that are ussually are more reputable. Thanks for the help.

I have noticed that NOD32 has produced these errors when I have it installed on desktops behind the proxy.
