In my .aspx page, in a form, there are a few hidden fields which are being used, which I use to
store information. Now, its always possible for a rogue user to view the source html/jscript of a
page and modify some values and submit the form with doctored data ... I was wondering whether
there is built in functionality in ASP.NET to prevent this behaviour - specifically, preventing a
user from manually modifying the values for hidden fields (e.g, saving the page on his local
disk, modifying the values keeping the form's ACTION url the same, then opening up the doctored
version in a browser and pressing submit).
