How to make a redirect and keep the query string?

Question

I want to make a redirect and keep what is the query string. Something like self.redirect plus the query parameters that was sent. Is that possible?

Answer 1

newurl = '/my/new/route?' + urllib.urlencode(self.request.params)
self.redirect(newurl)

Answer 2

You can fetch the query string to the current request with self.request.query_string; thus you can redirect to a new URL with self.redirect('/new/url?' + self.request.query_string).
