Hello all,

I'm building a Seaside (version 2.9) component for uploading files directly
to an Amazon S3 bucket. For this AWS supports HTTP POST requests, see

I can create the form that fulfills the AWS specifications, with one
exception: Seaside adds two hidden parameters to the for _s and _k This
breaks the AWS security checks on the form parameters.

These parameters are not required when posting to an external website. Is
there an easy way to remove them in this situation?
