Whether or not a proxy acts upon a 302 (which is called "recursion") is a
configuration option for the proxy. Nothing in the specification mandates
where this behavior should lie. A UAC can explicitly request proxies to
recurse, or not recurse, by using caller preferences, which has a parameter
for this purpose.
