Yes.

Ok, problem solved (I think). It turned out not to be so exotic an issue.
I modified the web server program as follows:

-    (format s "HTTP/1.1 ~S~%" (if fn 404 500))
+    (format s "HTTP/1.1 ~S~%" (if fn 200 404 ))

If I understand HTTP correctly "404" in the header means "file not found".
"200" means "ok". "500" means server error. So we were both saying
"file not found" but then delivering the file anyway. If that's the case
then it is surprizing that FireFox worked and not surprizing that IE closes
the socket connection before we can send the file.

With this change both FireFox and IE now seem to work reliable
and identically for me.

Anyway, I will take a closer look at the HTTP standard to make sure
that our headers are correct and complete.
