 It mostly looked right except for the redirect field.  Depending on the
server side it might not look for a post value from the query string.

Try to put it into the bytes like:

(post-impure-port (string->url "http://xxx..
.")  #"redirect=%2f#3fdnode%3dState&username=xxx&password=...")

And see if that helps,
