Closing file pointer

Hi All, Suppose I'm opening a socket connection to a server on some port, and I do some transactions, and generate html. But I 'm not closing the file pointer(socket). Only after the user clicks 'logout' or something should I close the file pointer. How do I do this?? I'm not understanding how to keep track of the file pointer, even after generating the html. Help. -- V Suresh --------------------------------- ANTI SPAM: http://india.cauce.org
