Can only one time send from server to client

Hello everybody!

I am LwIP begginer and i wrote one program with the LwIP(raw-api) but my program dont run very well.

My program can send only one time the information from Server to client.

Why can i write from server to client more that one time with the same connection?

My program is the adaptation from the programs httpd.c and shell.c LwIP's sources.

Can someone help me please?

Thanks a lot

Mauricio
