[Webtest] Using different Web Protocols?

[George Policello]

Does anyone have a way to put various handlers on incoming pages,
    <invoke ...>?

That is, I would like to use some trigger, for example, mime type, to
select a different parser for things such as

* WML or mime =3D=3D text/vnd.wap.wml
* text/plain
* WapMultipart
* WapXhtml
* etc.

My guess is that this has to be done at the HtmlUnit level but if
someone can offer an example, it would be most appreciated.

Thanks for any suggestions,
George
