need PHP help
 

i need some help writing a simple php script... or just someone to do it for me... here's the general idea:

1. hits come in to a url like this: mydomain.com/in.php?source=acct

2. script decides which of my sites to send the hit to (the target), based on a percent that i have set. so like if i have 3 sites in the script, i can have it send 50% to one 25% to another, 25% to the third, etc.

3. info is logged: unique or raw (per source), source of hit, target of hit

4. hit is sent to the target.

sounds pretty simple, but i need this to be able to handle about 200,000 hits a day to start... and not kill my server...

hit me up on icq or post here if you know a good solution :)
