Well, this is not JQuery related, but I want to know the current best practices in AJAX developments...
In an AJAX apps, such as user registration, we might have a API for user to check if their desired user name has been taken by another user. If we expose this API using AJAX, then it might become very easy for other people to automate a computerized bot to query our system. Are there any plattern(?) to provide some kind of security to the apps such that bot can be prevented? Thanks.
