* Implementation note:
*
* A number of these tests involve the rewrite valve returning a HTTP Location
* header that include un-encoded UTF-8 bytes. How the HTTP client handles these
* depends on the default character encoding configured for the JVM running the
* test. The tests expect the client to be configured with UTF-8 as the default
* encoding. Use of any other encoding is likely to lead to test failures.
