Hi
I am try to run something like this in my cgi.
-------------------------------------
system ("sleep 3000 &");
-----------------------------------
Since, it is time-consuming task, I let it run in background and
immediately return to user. I tested this script. It was no problem for
a standalone perl script. However, once I had this script in a perl cgi.
The script seemed not to have this system command run in background. It
waited there for the child process to finish.
Any clue for why it behaved like that? How can I for a child process in
background and return immediately to the web user?
Help is really appreciated!
jiesheng, please take a look at:
http://perl.apache.org/docs/1.0/guide/performance.html#Forking_and_Executing_Subprocesses_from_mod_perl
it explains how to do this sort of things.
