    Mysql Config/Spawn more processes

    I need to know what governs the creation of mysql processes, and how I can limit them. I've got a linux server running Mysql/Php to host a popular website... It averages about 150 requests per second. The hardware is a dual athlon MP with 1 gig of ram. Every so often say once every other day...

    session_id() returns &quot;&quot; [very impt!]

    What POSSIBLE SCENARIO makes the session_id() function return null???? I have a website where <i>SOMETIMES</i> when you visit the main page, your session_id() is blank. This causes a problem, for it means that session_start() is not maintaining the session for subsequent pages. The problem...

    Yet another PHP beginner that can't use the header function

    I think everyone is diagnosing this wrong. This code works for me: ---------TOP OF PAGE HERE--------------------- <? session_start(); header(&quot;Location: http://www.yahoo.com&quot;); ?> ---------------------------------------------- Make sure you're not doing this: -----------TOP OF...

    HOW SESSION DATA WORKS

    Hi folks, When I'm looking at my server, I notice whenever someone starts a new session a tiny file gets created... This file has whatever session variables have been registered in it. MY QUESTION IS: Does session data get stored to ram? Will extensive use of session data gobble up ram, or...

    Asp on a Linux server?

    Well program secrets put things in very good persepective, but i have a helpful tip. I was in the same boat you were in a few weeks ago. If you are not familiar with SQL stuff, as was the situation for me and are going to mySQL/PHP (which I did), use this lil script called PHPMYADMIN. It...

    session nightmare

    Dude fellas, sorry ignore this post. I just jumped out of bed to discover that this post doesn't make coherent sense (too tired maybe?). Of course my variable wasn't going to change cuz I kept resetting it back to 5. Solving this simple example isn't near helping me with my larger problem...

    session nightmare

    The php manual has conflicting data on this issue, and I keep hearing different things from everyone. I have one variable that I need to be constantly updated.
