Help with a download script

mlsbraves

I've searched and asked and can't find any script that does what I need.

Reference: http://www.phpbuilder.com/board/showthread.php?s=&threadid=10219149

So I now am deciding to create a simple one but I need some help. I want the script to go through a list of servers and each time the file is requested, it chooses the next server, so that it rotates the servers so theres an even load on them. I also want it to check to make sure that it gets a valid connection(because the server might be timed out or reached it limit) and if not, go to the next server on the list.

Lets say 5 people want to download the file (and I have 4 servers with the file):

First person goes to download the file and the server checks to make sure that server1 is good and if so it connects him to server1. (If not, goes to server2.)

Second person goes to download the the file and the script starts with server2. If good connects to it.

Third person goes to download the file and it tries to connect to server3 first.

When it gets to the end of the servers it goes back to server1.

Does everyone understand what I'm trying to say or do I need to explain it better?

Thank you for your time, I hope you can help me.

Yea I get what you want.. Like a Server Rotator Kinda thing.. Well. Im not exactly sure how to do it.. But maybe something like

counter script.. for each server and if server 1 is 900 and server 2 is 899 they goto that.. but im not exactly sure on what to do.. But it seems quite a clever idea

I tried a Google search for 'load balancing PHP' and, amongst others, found this

I'm still looking at the script but I don't think it will work. I'm not hosting the file on my server, it will be hosted on other peoples servers. This script checks my Apache's server-status information to determine when to go to the next server or mirror. Since the file won't be hosted on my server, I don't think this would work. Correct me if I'm wronge. Would this script I'm talking about, be hard to create? It doesn't seem like it, but what do I know.

Try that, Its not exactly what you are looking for, but you may need to modify it

Its a really nice download script, I have installed it and I do like it, but, it does nothing that I need. Its mainly just a download manager. I need something that will rotate the download between servers.

Is there member of this forum that has written small scripts in the past to help other members out? I really need this script and I can't find anything close it anywhere.
