[lwip-devel] http post and connection not closed problem

[Stephane Lesage]

Hi,
 
I wrote an http server in my embedded device (using sockets)
and sometimes I have a problem when uploading a big file (new firmware).
The web browser hangs (IE or FF on WinXP).

Looking at the IE capture, I can see:
- my device sends a HTTP 400 Bad Request response (packets 193, 194) (which is 
certainly a bug from me)
- closes the connection (packet 196)
- the web browser has not yet finished sending the POST data and tries to 
continue
- infinite loop with ZeroWindowProbe / ZeroWindow
 
In the FF capture:
- I don't see my device response
- infinite loop with RST,ACK from my device and TCP retransmission from the PC
 
 
I think the connection should be closed and the browser should display an error 
message.
Am I right ?
 
Can this be related to bug 26672 ?
Or is it the close/shutdown problem ?
