I submitted this as an improvement request a while ago and it (or some
variant) might already be in latest Seaside 2.9?

Subject: [Seaside] post form to external website

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?
