Since Russian Wikimedia projects are HTTPS only and have HSTS enabled, we should set its wgCanonicalServer to HTTPS, so that Bing will update the links to HTTPS.

A similar hack was in place in Russian Wikinews. The resulting configuration was vulnerable to man-in-the-middle attacks, as it depended on users first loading the insecure version. It also caused a major performance hit for users due to the double-loading. In consultation with Russian Wikimedia community members, consistent with our long term HTTPS rollout objectives, and consistent with the pre-existing request to participate in the HTTPS beta, we superseded the hack with a server-side redirect and HSTS as a secure and consistent default configuration for all Russian language projects.
