[squid-users] Proxied JSP pages load in Firefox/Safari but not IE?

One of our users is trying to access JSP pages over HTTPS (assume
https://foo.com/foo.jsp).

When the page is accessed through the proxy with Internet Explorer
(Win32), a blank page is rendered (and a subsequent View Source
reveals only skeletal HTML, no content). When the page is accessed
WITHOUT the proxy in Internet Explorer, the page is rendered
correctly. When the page is accessed through the proxy with either
Firefox (Win32 or Mac) or a different browser like Safari, the page is
rendered correctly.

Tailing the access.log file confirms that in all cases, the requests
are going through Squid (2.5S9). The proxy setup between the browsers
is identical (issued via a PAC), and all other web pages and sites
load fine in Internet Explorer through the proxy. The only problem is
this one JSP-driven site.

I've searched Google and the squid-users archives, but have come up
empty-handed. Any ideas?
