The following code implements a very basic HTTP server with server-side push. The server sits at port 5012. When a client requests a file, the server sends the file and begins to monitor the modification timestamp on the file. If the file changes, the server pushes a fresh copy to the client.
The code provides examples of the use of POSIX thread functions, including those used with thread creation, thread-specific data, and cleanup functions.
The read_line code handles both UNIX and PC flavors of end-of-line sequences (which makes it somewhat complex).
Oh, and the code is nicely commented and all that. Enjoy!

To use the push server, you must run Firefox or Netscape and connect to http://<machinename>:5012/<filename>. For my example, I used filename = test.html. Then, I ran a simple script that changed test.html. You can access test.html, the script (swap.sh), or simply download all the necessary files here.
