I had had my sever some of my other pages not work at times cause of to manny connections, is there a way to limit connections from my phpproxy site?
You could possibly use either a file or a mysql database to count how many people are using your connection and set a time out after X amount of time. If the useage limit is reach have it show a to many connection are being used page instead of allowing them to use the proxy and/or direct them to another proxy server instead.
