3.8 Can I launch a long process and return a page before it's finished?


[UNIX]
You have to fork/spawn the long-running process.
The important thing to remember is to close all its file descriptors;
otherwise nothing will be returned to the browser until it's finished.
The standard trick to accomplish this is redirection to/from /dev/null:

        "long_process < /dev/null > /dev/null 2>&1 &"
        print HTML page as usual
