Change RECV_BUFFER_SIZE and MAX_HEADER_READS as required. You can find the size by looking at the contents that webpage sends during post method. You can do this using wireshark.
The function to process “POST”method is as follows.
if( freescale_http_sessions[session].headertype == TYPE_POST )
{
collect_sensor_data( );
if( filename[0] )

if(passwd_flag ==1)

} // end of if TYPE_POST
