errors in post request

hi everybody,
i am new to libwww library. 
i am developing application which works like a proxy
server. it receives request from browser, and it will
forward that request to remote server using libwww
library and sockets. 
i am getting errors while getting data  from remote
server in post request.
when the first time request goes to server through my
application, server is responding properly and getting
data, but when the second request goes to remote
server while reading the data from the remote server i
am getting the following error.
from HTDialog_errorMessage() function of HTDialog.c

Fatal Error: 403 Forbidden (Forbidden)

anybody helps me in this greatly appreciated.

thanks & regards,

venu
