Try :<br>

<div>Hi Bogdan,</div>

<div>I'm not looking to process a received 302,
but rather generate one of my own. I want to
set the q values so that the other side will
serially fork. Ovidiu's example [1] from
earlier in the thread doesn't address this.
Looking at the docs for append_branch() [2] or
rewriteuri() [3] I don't see any mention either.</div>
