[Mediawiki-l] Mediawiki extension API

[Jean-Christian Imbeault]

I've read the meta-wiki information page on writing your own mediawiki 
extension but I have a question on behaviour.

If you write and extension does the tag (extension) get evaluated every 
time the article (page) is loaded or just once and then stored in the DB 
as is?

Is it's the latter, is it possible to have truly dynamic content using 
media wiki? By this I mean writing an extension that will generated 
(possibly) different content every time the article is requested.

I have content that is generated every day on my server and I would like 
to have it loaded into an article. I've written an extension that does 
this but it seems that the content is just loaded once, and then saved 
to the DB. I'd like to write something that went and *always* fetch the 
content dynamically off my site system (or whatnot).

Thanks,

Jean
