Anyone, have some stratigies to validate query strings if they are not valid and where to do it?
I am running a web app that is about 20 files, using Master Pages. I have 5 common id's I pass (1 per page).
My biggest question is if a user deliberly changes the id to a string what should I do. I validate it then send the user to where? I'm using many gridviews and I don't want any actions to take place. If I do a try catch how do I perform any more code from executing.
by default, expections will push the user to a error page. Is this common for ASP web apps?
Should I validate each page seprately and then duplicate code, or have one page that validates everything?
