24 * Redirect to another page or external uri. Kind of PageAlias.
26 * <<RedirectTo href="http://www.internet-technology.de/fourwins_de.htm" >>
27 * or <<RedirectTo page=AnotherPage >>
29 * Author: Reini Urban <rurban@x-ray.at>
32 * Todo: fix with USE_PATH_INFO = false
34 * This plugin could probably result in a lot of confusion, especially when
35 * redirecting to external sites. (Perhaps it can even be used for dastardly
36 * purposes?) Maybe it should be disabled by default.
