Topic on Extension talk:RSS/Archive 2

Does $wgRSSUrlWhitelist allow for a wildcard operation? I want to allow a feed from a specific domain and any feeds located on that domain.

For example if the domain is https://foobar.com. Then https://foobar.com/feed, https://foobar.com/category/technology/feed, https://foobar.com/tag/events/feed, etc. would be possible (assuming those are all valid RSS feeds). Using the parameter would I need an entry for every possible feed or can i just say something like https://foobar.com/* as a catch-all?

I found my answer in Phabricator. I was looking for the wrong terms. :) task T47857 According to that task the RSS extension does not work with "protocol relative urls".
