back button/link

[eluser]crwtrue[/eluser]
In my program i first get some values to prefill a form which user then submits to view some data. I put in hiddenfields the values that the function which pre-fills the form uses. I have a anchor()-function which links back to that prefill function and i use concat to pass the values which is are then readed uri segment. Is this a normal way of doing this kinda thing?
