Manual:$wgAllowExternalReqID

From mediawiki.org
HTTP client: $wgAllowExternalReqID
controls whether MediaWiki accepts the request ID set by the incoming request via the "X-Request-Id" header.
Introduced in version:1.34.0 (Gerrit change 505668; git #I605471f)
Removed in version:still in use
Allowed values:(boolean)
Default value:false

Details[edit]

If set to true, that value will be used throughout the code as the request identification. Otherwise, the sent header will be ignored and the request ID will either be taken from Apache's mod_unique module or will be generated by MediaWiki itself (depending on the set-up).
