1 Content from sites such as YouTube can be embedded into a web page. Maybe
2 you want to do this. But you'll find that the [[plugins/htmlscrubber]]
3 doesn't let you. It blocks the tags used to embed such content, because
4 they can be abused in many evil ways.
6 Some plugins have been written to try to work around this problem, by
7 whitelisting the html needed to embed things from a few sites like Google
8 maps, calendar, videos, and YouTube. The problem with these plugins is that
9 they have to be kept up to date to add new sites, and follow changes to the
10 html such sites use for embedding.
12 (Digression: The real problem with the plugins is that they hide the
13 underlying trust relationship. If you decide to embed html from a site,
14 you'd better trust that site. And if ikiwiki lets you enter such html, it

18 You can configure it to skip scrubbing certain pages, so that content from

29 locked_pages => '!*/Discussion',
31 More simply, you might want to allow yourself to embed content anywhere
32 on the wiki, but scrub content written on Discussion pages:
34 htmlscrubber_skip => '!*/Discussion',
35 locked_pages => '!*/Discussion',
