In every request form data there's an 'x' param with value between 0 and 1 (ie. x:0.775084022898227).
It's different for every request.
Does anyone know what is it used for and can it be removed?

Re: x param in the form data2012-11-30T15:31:47ZThis is the accepted answer. This is the accepted answer.Not sure where you're seeing this, but it's fairly common to add a random number when submitting form data to prevent people from accidentally re-submitting.
As a general rule, you shouldn't remove or change things you don't fully understand, it may cause bugs that are hard to track down.
