In order to evaluate the effectiveness of social sharing and other similar efforts for Wikimedia projects, a parameter "wprov" can be appended to URLs on a case-by-case basis. This page exists to keep track of reserved values.
The value of this parameter will be recorded in the X-Analytics field of the webrequest table (as
x_analytics_map['wprov']). Requests with different "wprov" values will not be cached separately (as it would be the case with other, arbitrary parameter names), thus avoiding cache fragmentation.
The wprov parameter is dropped when a user is redirected to the mobile version of a site (T252227).
Description of wprov parameter
The format of the parameter name is ?wprov=<3_char_feature><platform_one_char><major_version_of_feature_uint>.
