[edit] Blacklist?

Even though there seems some protection by permissions, perhaps some things should be black-listed: http-equiv="set-cookie" comes to mind, and http-equiv="refresh" may be problematic too - and there are probably more.

Thanks for the excellent suggestions. I'll add them to the issue list on Issue #11.

Regarding the permissions: if an admin adds a meta tag to an unprotected page, and the page is the edited by a non-admins, the meta-tag will no longer be executed, right?

true.

This seems a bit counter-intuitive and tricky to maintain, especially since there seems to be no way to see that problem... -- Duesentrieb ⇌ 10:39, 5 January 2008 (UTC)

I see your point. The reason I put this sort of functionality is because on the wikis I administer I only admit editing of the talk pages and I can be bothered to protect the normal pages all the time. Jean-Lou Dupont 18:45, 5 January 2008 (UTC)

[edit] XHTML

Only a small thing, please add the /> at the end of the Metatag to make it fit into XHTML. 77.182.28.2 01:51, 3 February 2008 (UTC)

[edit] Description

I tried to make the description a little more user friendly:

Allows users to add META and LINK tags to an individual page's HEAD coding. This extension still allows the mediawiki page to be parser cached.
