Hi Can ISA server 2000 pass outgoing internet traffic on non-standard HTTPS sites, using web proxy service only? There is a site https://webmail.waiariki.ac.nz:50443/servlet/webacc I want to get to and I get a page not found error. But the site is there as I can connect using the firewall client. What configurations would I need to allow traffic. ? Thanks. RajiA Email disclaimer: This email and any attachments are confidential.
