Ah, yes now I can confirm there are definite problems accessing the
"gcl simple web server" using IE 6. I have been testing using Firefox 1.0.3
and oddly exactly the same url works fine with no aborts.

No I think you are right (we are both right :). There is a problem
when using Internet Explorer. IE must be making rather different
socket calls than FireFox. That seems quite odd to me.

Using IE, the problem seems to intermittant. It works for a while
with some urls and not others.

Here is a typical failed test using IE.

Then using Microsoft Explorer 6 sp2 and url
 http://localhost:8085/msys/1.0/
I get the following error:

Does this back trace help to see what's going wrong?

If I start again and do the same thing using FireFox I get:

Loading test-http2.lsp

And the list directories appears in the browser.

Let me know what I can try next.
