24 * Redirect to another page or external uri. Kind of PageAlias.
25 * Usage: <?plugin-head RedirectTo href="http://www.internet-technology.de/fourwins_de.htm" ?>
26 * or <?plugin-head RedirectTo page=AnotherPage ?>
27 * at the VERY FIRST LINE in the content! Otherwise it will be ignored.
28 * Author: Reini Urban <rurban@x-ray.at>
32 * This plugin could probably result in a lot of confusion, especially when
33 * redirecting to external sites. (Perhaps it can even be used for dastardly
34 * purposes?) Maybe it should be disabled by default.
36 * It would be nice, when redirecting to another wiki page, to (as
37 * UseModWiki does) add a note to the top of the target page saying
38 * something like "(Redirected from SomeRedirectingPage)".
