post versus get (through Mason)

(Still working on getting Kwiki to run inside Mason...)

Is there a way to specifically inject the posted values into the calls to Kwiki?
 It appears mason is doing something to the posted values but "get" values are
passed through without a problem.

I've filtered the pages and javascripts coming out of Kwiki to convert any
"post" into a "get" and I can now edit a page as well as update my preferences.
 But obviously these should be posts...

Thanks,
Paul...
