Disable escaping of ActionController::Base.url_for



I am trying to use rails for a wml/wap application. Submitting forms
with wml goes something like that:


The wap browser replaces $(search) in the url with the text entered in
the input field. Now to my problem.

To use the routing information of rails I would like to use the method
url_for. The problem is that this method is automatically escaping
$(search) to %24%28search%29, and so the wap browser is not submitting
the input field correctly. Is there a way to diable the escaping? Maybe
some other tips?
