|Domains that may make cross-site Ajax requests to the MediaWiki API.
|Introduced in version:||1.16.0 (r54127)|
|Removed in version:||still in use|
|Other settings: Alphabetical | By function|
Allows Ajax requests from certain domains to make cross-site requests to a wiki's API (see Manual:CORS for example usage). This uses the Access-Control-Allow-Origin HTTP header. Note that some older browsers don't support this. This only affects requests to the API. Other entry points (index.php) are not affected.
The value must be a list of allowed domain names, which can include shell-style wildcards (
? to match any character,
* to match any number (including zero) of characters).
An empty array means no external access is allowed.
Allow any domain to access the API via Ajax (This is insecure):
$wgCrossSiteAJAXdomains = [ '*' ];
Allow two specific domains:
$wgCrossSiteAJAXdomains = [ 'en.wikipedia.org', 'en.wikibooks.org' ];
Allow all subdomains of a domain (including "deep" subdomains such as
$wgCrossSiteAJAXdomains = [ '*.wikipedia.org' ];
See gerrit:9624 for a usage example.
Until MediaWiki 1.34, there could be logs
Non-whitelisted CORS request with session cookies referring to the wiki itself, which could be fixed by adding the wiki’s server name in this parameter to avoid these logs.
This was fixed in MediaWiki 1.35 in T243908.
