Setting POST Method and Multi Parted Requests

Hi,

I have two questions regarding Cactus tests I am currently writing.

Firstly, I would like to test the POST, GET, PUT and DELETE methods for 
a servlet I am working on. Unfortunately I am unsure of how to actually 
set the HTTP method within the Cacutus tests.

Secondly, how do I set up a test for a servlet which recieves data which 
is uploaded to it using the multipart/form-data encoding.

Thanks in advance,

Imran
