I'm uploading a clients website early next week and they've just informed me that they use load balancing software to distribute over two servers.
Normally this wouldn't be an issue because content is stored in the database and as long as both files areas can access it then it should be fine.
However, the issue comes in when uploading files. I've been informed that files should be uploaded to both servers.
I wouldn't even know where to begin to make this modification. Can anybody shed some light on it for me?
Is there a global method that's invoked when files are uploaded?
Note: This needs to work with the file field on several content types and even when files are added through modules/cck
