sending http url through http socket programming..

hi
am senthil
am developing a software to send and receive SMS using HTTP connection

first of all am forming a URL and sending that URL to a remote server using my Client Program
i send that url through Socket(using Send() Function)
if i send more than one URL one by one using the same descriptor ..
only the first message got hit in that recepient server ..
rest of the messages are not hitting in that server ..

i could'n trace the problem ...

But using my own sample server program with the same Client program i can hit that server ..
and i can view the messages in that sample server program..

am using only single socket descriptor to send multiple messages ..
i did'n close the descriptor..
since i want to send SMS continously..

i need some suggestions..
