$smwgSparqlRepositoryConnectorForcedHttpVersion is a configuration parameter that sets whether CURLOPT_HTTP_VERSION should explicitly be forced for the endpoint communication. It was introduced to mitigate errors being encountered as being described in issue #1306.1 The configuration parameter was introduced in Semantic MediaWiki 2.3.1Released on 4 January 2016 and compatible with MW 1.19.0 - 1.25.x..2

The setting of this configuration parameter should not be changed unless issue #1306 is being encountered1 due to the following note: "... libcurl to use the specific HTTP versions. This is not sensible to do unless you have a good reason."3

Default setting[edit]

$smwgSparqlRepositoryConnectorForcedHttpVersion = false;

This means that CURLOPT_HTTP_VERSION will not be forced for the endpoint communication.

Changing the default setting[edit]

To modify this configuration setting, add one of the following lines to your "LocalSettings.php" file after the enableSemantics() call:

Force CURLOPT_HTTP_VERSION for the endpoint communication
$smwgSparqlRepositoryConnectorForcedHttpVersion = true;

This means that CURLOPT_HTTP_VERSION will be forced for the endpoint communication. Options are available as specified at <curl.haxx.se> (CURLOPT_HTTP_VERSION).3

Important noteImportant Note: Do not change this setting unless you know what you are doing!
