How does Laravel handle PUT requests from browsers?

Question

I know browsers only support POST and GET requests, and Laravel supports PUT requests using the following code:

Answer 1

It inserts a hidden field, and that field mentions it is a PUT or DELETE request

See here:

echo Form::open('user/profile', 'PUT');

results in:

Then it looks for _method when routing in the request.php core file (look for 'spoofing' in the code) - and if it detects it - will use that value to route to the correct restful controller.

It is still using "POST" to achieve this. There is no ajax used.
