We are an ISP in Wisconsin that runs a web caching/filtering service for
our customers. Many of our customers use a local Boarder Manager proxy
that forwards the request to our centralized proxy. Since we have upgraded
the software in our centralized proxy (Blue Coat SG4.x) any htpps traffic
coming from Border Manager is denied. Blue Coat states that there must be
something in the headers from the Border Manager that the Blue Coat is not
liking. We are fairly unfamiliar with Border Manager on our end. Does
anyone know what kind of header info could go in to https traffic that
could be causing any problems? Could it be trying to use a different port
other than 443?
