I'm trying to compile a version of squid with the front-end-https option in order to reverse-proxy for our Exchange 2003 OWA server. The squid server is a Gentoo Linux box, so the newest package available through emerge is 2.5.9-r1 which doesn't recognize front-end-https. After compiling squid-3.0.PRE3 with ./configure --enable-ssl, I get the following error with squid -k parse: 2005/03/16 19:06:41| parseConfigFile: 'squid.conf' line 5 unrecognized: 'front-end-https=auto' Below is the config file I'm using, cobbled together from Henrik Nordstrom's suggested config file and one that works when reverse-proxying for our old Exchange 5.5 OWA server: Thanks for any assistance.
