You can download it from here: http://sme.scarlet.be/~vip107/WebServ.zip
The url for your code is bruno.html from the root (see source).

I've downloaded it, and got the same thing. I disabled Windows Firewall, but
nothing changed.
I've uploaded an image in http://www.revolution.com.br/icsscreen.zip
It has a readme and some marked areas to show what happen here.

I have real world applications running with the HTTP server component and
they have no problem at all. So it must be something on your system.
Do you have another computer to test with ?
Can you make the server run on one computer and the browser on the other ?

My system has all updates, but this happens also on other machines (I can
put the server in my machine or in other machines and the same happens).
The program runs fine, just the connection isn't closed, you can have many

Hello Bruno,
I just downloaded the demo from Francois, and tryed the server on 3
different machines (NT, W2K, XP), and every time connected with the 3
machines with IE (different versions) to the server/bruno.html. Works
every time here.
Also I have a several project with the HttpSrv without pro
I begin to think that this is the problem - I was thinking two options:
something with the Brazilian Portuguese version of IE, or something with a
program that intercepts communications, like an antivirus.
The only questions that remain are: why does this happen only with virtual
pages and not wit

Yes, I know, but the behavior is very consistent to be just coincidence.

Some ISP block port, but not all port, probably all above 1024 is open,

You can easily built a dynamic page that return exactly the same
informations than a static page. If you try that, verify using a sniffer
that the output is exactly the same.

Finally, I could find what was causing the problem here - I still don't know
why, but at least I could fix it.
I analyzed the header files sent by a virtual page and an identical real
page. The difference was the virtual page was not sending three lines:
Accept-Ranges: bytes

Does it depends on the size of the page ? You send 5000 lines in your test
but what is the minimal size to experience the problem ?

Hello Bruno,
I'm just bsy in a rather large project using THttpSrv, and this is exact
copy of what I send in all my virtual pages:
Header := Cli.Version + ' 200 OK'#13#10 +
'Content-Type: text/html'#13#10 +
'Content-Length: ' + IntToStr(DocLen) + #13#10 +

I finally managed to track what is happening here - in Internet options, if
"Use HTTP 1.1" is unchecked, this behavior occurs when there is no
"Connection:" in the header, thus causing this problem when virtual pages
are sent.

I think the problem is not with the size of the documents - I've had some
problem with the Time demo, which is very small.
Try this - go to Internet Options, Advanced, and uncheck Use HTTP 1.1. With
your header, the server you are developing should show the same behavior
I've seen.

Taking a look at SendDocument, I saw this:
{ *DAVID* Revised this if/then/else }
if FVersion = 'HTTP/1.0' then begin
if CompareText(FRequestConnection, 'keep-alive') <> 0 then
Header := Header + 'Connection: Close' + #13#10

Header := Header + 'C
