You might want to use $arg_id here (i.e., the $arg_<name> variable for<br>
the <name> argument).  Otherwise, it won't work if any other arguments<br>
are given.<br>
<br>

I don't think that's allowed.<br>
<br>

What doesn't work?<br>
<br>
I would think your<br>
<br>
> location = /test/place {<br>
<br>
block would work, although not as shown, but I assume you just left<br>
out the part that normally handles the request.  It would handle the<br>
requests for id=1 and id=3 as before, and it's just the id=2 case that<br>
gets redirected, right?<br>
