Hi!

I have an application/a script that is run from another application.
The script is mostly working as a HTTP client but in some cases it also =
has to act as a HTTP server.
Basically just for serving a few files. The files are dynamically =
created by the script when needed.

To accomplish this I'm trying to use subprocess Popen
and an extremely simple web server script which basically contains:

    Handler =3D SimpleHTTPServer.SimpleHTTPRequestHandler
    httpd =3D SocketServer.TCPServer((hostname, port), Handler)
    httpd.serve_forever()

In the main script I do:

    op =3D Popen(popen_args, stdout=3DPIPE, stderr=3DPIPE)

When the main script is done it closes down the HTTP server by doing:

    op.terminate()

The problem I have is that if the main script is run again almost =
immediate then the old HTTP server=20
process doesn't seem to have released the port yet. So setting up a new =
server fails.

Is there anything I can do to get the port released immediately when the =
tcpserver is terminated.
Or is there another way of doing this that will work better ?

Roland
