This is interesting - I've investigated further.

Take any version of squid (I've tried two different ones) and configure
IE6 to use it as the proxy for all protocols.

Now try and access:

https://somewebsite.withareaonsable.long.name.com:446/

446 is not a safe port so you'll get a warning. You might find that the
error is truncated if its long enough. I found it removed part of the
hostname at the bottom of the page and </BODY> etc was missing.

You might need to increase the error page by 1024 bytes to see the problem
as I found my older squid 2.4stable6-6.6.2 (RH) had a maximum size of
830 bytes not 1128 like the later version.

This is a completely and easily reproducable bug (probably in IE) but it
exists non the less.
