process handling

I have a perl cgi script which executes a program using `` what I would like to do, is start the process and then immediatly send the response back to the user, without waiting for the process to finish.

In other words: the user makes an http request, the script starts a process, sends back the response, and some time later the process finishes (without anyone really knowing about it).

How can I do this?

thanks

You could merely append an ampersand (&) to the end of the system call:

  `/some/process arg1 arg2 &`;

In the case where the other process is as described by japhyrpi I somewhat agree that the & method works, if the OS is one that supports the & method.  

The things I do not like about this is that: 1) it does not take advantage of multi-threading where implemented, 2) it is OS specific, 3) it does not allow the rest of the work to be done in the same perl script.

But, I do agree it will work with these restrictions.
jhurst - well, fork() is OS dependent too.  ActivePerl has only recently provided support for it.
correct.  However, fork() is defined in perl, the & is not.  Also, most decent multi-tasking operating systems implement fork() therefore it makes its way into perl there too.  Now, MS products are of course a different issue.
