Can i rely on that every browser will only send the POST data from the form they were posted from, or is there some browsers that sends additional data along?
The reason i am asking is, that i have a form with a lot of fields, that may only be numeric. So the easiest validation would be to just run it through a function that checks if every field is numeric.
The browsers that i have on my machine, only sends the fields from the form, so i'm hoping that goes for every other browser.
