Rewriting feed URLs

I've finally got my RSS feeds back up and running. The issue ended up being the fact that I'm running my wikis in the site root directory, i.e. without the /wiki/ in the URL like Wikimedia sites have. I've never liked the redundancy of it, and especially with .wiki domains it looks a bit silly (e.g. freo.wiki/wiki/…).

I thought for ages that it was because of the precedence of RewriteRules within Directory sections vs those within VirtualHost sections, but that was a red goose chase. It was actually that MediaWiki prioritises the title it finds in PATH_INFO over one supplied in the query string, so /Foo?title=Bar is seen as having a title of Foo instead of Bar.

To fix it, I turned off $wgUsePathInfo, set the $wgArticlePath to include the full domain name (bad, perhaps; this might come back to bite me), and then appended the path info as {{{1}}} in a rewrite rule. So the Apache config looks like this:

<Directory "/var/www/mediawiki">
	RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} !-f
	RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} !-d
	RewriteRule ^(.*)$ %{DOCUMENT_ROOT}/index.php?title=$1 [L,QSA]
</Directory>
<VirtualHost *:443>
	DocumentRoot /var/www/mediawiki
	RewriteRule ^/news.rss /index.php?title=Special:CargoExport&table=posts&… [NC,QSA]
</VirtualHost>

And the MediaWiki config like this:

$wgScriptPath = '';
$wgArticlePath = 'https://' . $_SERVER['SERVER_NAME'] . '/$1';
$wgUsePathInfo = false;
