Forms Browser Support
For reasons of (apparently) sheer inertia, HTML4 did not require browsers to support HTTP verbs 'PUT' and 'DELETE' in forms. This is arguably a horrible oversight, and certainly a sticking point for REST-in-a-browser.
Problem
HTML UAs only support two verbs, POST and GET, per HTML4 spec.
The new WebForms 2.0 spec extends it and allows using multiple verbs:

This spec is not part of W3C work, although W3C acknowledged it:

Proposal
We propose to work with Firefox and Safari to get them to section 5.6.1 of Web Forms 2.0 (which hopefully will push IE to do so as well). While that will not solve the legacy problem, it will at least allow developers to write to this paradigm, even if they have to fake it in some cases for backwards compatibility.
Solutions
Compatible versions
Bugs & Patches
- Firefox ?
- Safari ?
- Internet Explorer ?
Workarounds
AFAIK, there are no plans to implement Web Forms 2.0 in MSIE natively, but there is an effort to provide a JS-powered implementation:
