I'm trying to find a script that goes through a list of servers and chooses one to download from. I'm looking for something close to download.com's download script. I have a file that requires several servers because of bandwidth issues and I want it where when you go to the downlaod page it will choose from the list of servers the best one. I have already looked through hotscripts.com but didn't find anything. PHP would be prefered but might be able to use perl.
I'm not sure excactly what metric I want to use but just something that would check to see if the connection is made and if it is to start the download from that source and if not go to the next server.
I will be hosting a file that gets a lot of hits a day and becuase of bandwidth issues, some of the servers might run out of bandwidth for that time, so that is why I have several servers to host this file.
Are there any script that comes close to doing this?
