It's not really related to the issue at hand, but instead of issuing a
sendPageAndWait() to a pipeline that just calls another flow function,
you could call that flow function confirmStage() directly and save some
complexity.

IIUC, you're just making an HTTP request to an external URL, passing it
a few parameters, and getting back a one-line text result which you need
to parse? You can do that all within flow by using the HTTPClient
library: http://jakarta.apache.org/commons/httpclient/ (included with
Cocoon).
So instead of your form posting directly to the external site, have it
post to your continuation like normal, then in your flowscript read the
user's inputted values from the form, assemble them into a HTTPClient
request, send that request to the external URL, and parse the response
however you need to.
Is this what you're wanting to do?
