Validate whether its a human submitting a form and not a DOS :-0

Question

How do you ensure that whoever is submitting a form is doing it and its not some DOS attack?

I was hoping there was an easy way to generate some kind of image or squiggle that the user has to enter prior to submitting a web form

Technology Stack MVC with C#

These are called CAPTCHAs; http://stackoverflow.com/questions/450835/how-do-you-stop-scripters-from-slamming-your-website-hundreds-of-times-a-second — Alex K., May 13 '11 at 14:52

I'm assuming you mean that you want to check that it's not a bot (rather than DOS which is something else). For that, take a look at reCAPTCHA.
