Re: Http server implementation for Windows Media Server

Thanks,
I think I understand a bit more following your direction...
Now to a real case that I encounter, as described in the first post of this
thread, modifying in the tcp packet before transmitting, just the port of
the client as the port is usually different than the original one, causes a
real time sniffer to indicate a huge "relative sequence number". Leaving it
without modification causes an indication of 1 - just as it was in the
original packet. Why should the port value influence on that?
Can you explain that?

On the tcp layer, both server's and client's tcpip stack do that

Thanks,
Suppose a common scenario where a standard Web Server responds to a GET
Http request. Does the server ever ACKs the client and when?

Thanks

That strange that no ACK appear because any data should be ACKed

Hi all,

I'm trying to implement a specific Http server that listens on port
8080
(not the standard 80). Actually it resembles a Windows Media Server
that
also works as a HTTP server (among some other modes).
I have a dump file of prercorded transmision from an actual Window
Media
Server and Windows Media Player, and my server implementation should
transmit them after establishing the tcp connection with the Player.
In reality, the connection is established but the server behaves with
the following anomalies-
1. After the "GET" transaction by the Player, the server transmits an
ACK which doen't appear in the normal case.
2. The first dump packet that is being transmitted starts with a huge
"Realtive Sequence Number" instead of a 1.

Can someone advise please?

Regards

Gur
