Hi Meadiawiki Team/Users,
I am currently preparing our Mediawiki to run with HTTPS behind Pound and Varnish. The setup went very well so far but now I have troubles with getting mixed content on image urls.
As Mediawiki is using protocol relative URLs (for images too?) I thought I don't have to setup much, if the protocol is detected correctly. Pound adds the 'HTTP_X_FORWARDED_PROTO' Header, and I've found the Mediawiki detection in includes/WebRequest.php: if ( ( isset( $_SERVER['HTTPS'] ) && $_SERVER['HTTPS'] == 'on' ) || ( isset( $_SERVER['HTTP_X_FORWARDED_PROTO'] ) && $_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https' ) ) { return 'https';
Therefore I assume that protocol detection works correctly. I have also enabled $wgSecureLogin to see if protocol detection works, and as far as I can see it does. I have also run
- echo $this->getRequest()->getProtocol();
on a Special Page, and this prints "https" even behind Pound. So Mediawiki should detect the Pound Header.
But images are still used with <img alt="..." src="http://..">, even if the page is called with https://.
Are any further steps to get images work with https? (e.g. set $_SERVER variables) Are images using protocol relative paths per default?
I am using
- Mediawiki 1.23.7 (987edf2) 09:58, 28 November 2014
OK, I've got the error now - ensure to use protocol relative URLs with foreign file repos: $wgForeignFileRepos[] = array( 'class' => 'ForeignDBRepo', 'name' => 'otherwiki', 'url' => "//www.example.com/images", [...]
Then Mediawiki is handling links/images correctly behind pound.
