Hello Experts,

i would be thankfull for an explanation what happens with HTTP(TCP/IP) transmissions when the server crashes unexpectedly, how does the client Browser (Firefox / IE) handle this event.

What happens in the following two standard cases:

Clients-actively sends data: The TCP/IP Connection has been estableshed and the Client (Web-Browser) is Sending a POST Request with some data and in the middle of the process of sending the server crashes. What does this mean for the client? As far as I know TCP/IP does not "acknowledge" a send data-package so the client does not know that the server crashed. How will the client behave? (Firefox and Internet Explorer)?

The Server is actively sending data: As above the tcp/ip connection has been established and the Server is sending a large website to the client (browser). In the middle of the sending-process the server crashes, so no futher packets are sent. How does the client browser react to this event (Firefox and Interne Expolrer)

Thank you very much!! Jens
