I am running BM 3.7 sp2 and IE 5.5 and 6.0.

Some developers would like the error messages to be meaningful for
testing
on our internal web site. If the browser goes through the proxy server

they receive a generic "500 internal error" message in the browser.
This
is the proxy error page. If they go direct(ie no proxy) they get
error on
line xx running test.asp.(Which is much more helpful in
troubleshooting).

I thought disabling show friendly HTTP error messages would do the
trick
but it does not seem too.
