Topic on Extension talk:MediaWikiFarm

This is now possible. See phab:T161413.

It seems that only individual domain names are supported for each wiki. Is that correct? Is there some way to have wikis installed side-by-side on the same domain in different subdirectories?

Yes, the only scheme is for now individual domains (or subdomains). You are interested in a feature "by subdirectory" I guess, isn’t it? If so, I can think about the changes needed to make it work.

Yes, that's right: the name of the subdirectory would determine the wiki. But don't worry about it, if it's not already part of it! :) I'm just investigating how I can convert a few of my wikis to this extension, but there are other ways I can do things. I'll see how I get on, and report back.

I began working on this feature (only locally for now) and I have still to check security and add tests.

The configuration for a farm "http://example.org/wiki1" + "http://example.org/wiki2" would be something like:

farmexample:
  server: 'example\.org/(?P<viki>wiki[12])'
  …

(see docs/config/farms.yml for the main config file)

I opened a task for this T161413 "Differentiate wikis per-path in addition of per-domain".

Is my understanding correct that this works now?

As I see, yes.
