HTML with Forms and how to handle Submit

[OleSan]

We're seeing more and more HTML-banner that want to use forms. I think it would be a good idea to have something about this in the spec, especially how we handle Submit in a good way, and perhaps include a sample in our Sample directory.

Any of you code gurus have thoughts on this and a best practice for handling it?

Submit with ajax and use window.open if it needs to open a landing page?

What kind of tracking considerations do we have?

I agree with @gregersrygg, submitting with XHR would be the solution for posting. When it comes to XHR there are differences in the browser implementation, it would perhaps make sense to have some recommended libs for cross browser XHR.
On mobile devices this isn't all that important, but if ads are targeted to desktops it would be useful.
