Classic form, how to submit to call a controller method?

[eluser]avastreg[/eluser]
The title is a little weird

I need to know if there is a best-practice/how to to handle the submit of a form with method=get to call a method of a controller.

An explanatory example:

in controller_A view i have:

Code:

<form action="/controller_B/method/" method="get">

<input name="foo" value="get_value"...

</form>

I need to reach

Code:

/controller_B/method/get_value

but with that submit i get

Code:

/controller_B/method/?foo=get_value

Is there a way to do this or i have to manage it in ajax?
