Dear Monks,
I have a front end Apache server with a backend apache mod_perl server. There is a reverse proxy that points to the mod_perl server from the front end. On the front end server I have the Timeout setup to 120 (The number of seconds before receives and sends time out.).

The issue comes down to MySQL queries that take over 120 seconds. I know I could just increase this number, but I would prefer to handle this in the programming.

So this makes me think about using Fork and sending some data between the client and server, but I have heard a lot of issues with this on forking the Apache process. Also, the bigger issue I see is when I use fork behind a proxy that I have to send a certain amount of data before the proxy sees the data (Not sure why).

So here is what I am thinking below (Very rough, but I think you will get the point)?

$SIG{CHLD} = 'IGNORE';
my $child = fork();

if ( $child )
{
    # Parent
    # .... DO DB Stuff
    sleep 10;
    
}
elsif ( $child == 0 )
{
    # child
    for (1..100)
    {
        print " ";
    }
    
    ## Add in clean up stuff here maybe??
    exit;
}

So would something like this work if I made sure the ProxyReceiveBufferSize was reached? Also, I do not want to send spaces or line breaks b/c it makes the results look very strange.

I am hoping maybe there is an entire different way to do this!!

Please let me know, thanks!
