Okay thx, I think the limit is 2083 characters. And if they find out the link or someone else stumbles upon it how do you protect the logs without password?
That's what Kulver is trying to explain. The link can be a blank page, no logs will ever appear there. The PHP script's function is to receive the POST data and save it on a file/database/whatever. You can later retrieve them using SSH, or FTP or whatever you'd like.
