I haven't run into this specific problem, but here are a couple of things
I'd try.
First, is the server hanging indefinitely, or is the browser hanging when
processing the redirect header? You can find this out by using a client that
doesn't support redirects, like telnet, netcat, or HTTP Analyzer
(http://www.coolfusion.com/). I wouldn't be surprised if it's a problem on
the client.
Second, if it does turn out to be a server problem, I can't see why it would
have to do with the variable output in the CFLOCATION tag as opposed to
writing the variable in the HTML page content. (Not that this means the
problem couldn't have to do with the CFLOCATION tag specifically, just that
I can't see how.) It might, though, have to do with a "timing" issue - you
might be processing the redirect so fast that the page to which you redirect
isn't ready for you! You might try delaying the CFLOCATION for testing
purposes, using a loop, to see what happens.
In any case, I'd be interested in the results.
