Unix Socket Programming

Socket programming
This is an example of using Unix Socket programming to do enquiries of an Ingres relational database.  This HTML fill-in-the-blanks form called a Perl CGI script on a windows intranet server running the Apache web server.  This then sends a request for data to the Unix server using a specific port/socket number.   The Unix server sits waiting for a data request on the port number - when a request is received, it breaks down the request and sets of an Ingres database enquiry.  This enquiry generates a file which is then streamed back to the intanet server which, in turn, creates the HTML page that is returned to the user.
