Objet : [lwip-users] howto put tcp packet together


Hi,

I'm using HTTP server in contrib. Unfortunately it assume  all data is 
in one packet. In my situation data is spread over several packets. I 
need to fit them together in the right order before processing. Any 
pointers how to do this would be great. What I'm especially looking for 
is the number of packets and a counter that specifies the order.

TIA

Gustl
