[{SET alias='PageAliases'}]
Every time someone views the page "Aliases", they will be automatically redirected to this page. This is very useful if you want to be able to use the irregular plural forms, for example. Normally, JSPWiki does recognize english language plural forms of pages properly, but it's not smart enough to recognize certain forms, such as "aliases".
It's also possible to redirect any page to some other page. The system administrator can set the "jspwiki.specialPage" -redirect from jspwiki.properties, but by setting:
[{SET redirect='http://www.jspwiki.org'}]
on a page, any visits to that page will be promptly redirected to "www.jspwiki.org".
Well, obviously you cannot click on the "Edit this page" -link, because you are redirected every time you try to view a page. You can, however, edit the page directly by just writing Edit.jsp?page=pagename after the base url.
