Tasks

• Ensure Redis uses password

• Ensure reCAPTCHA still works under SSL, related to 1d — SSL Between backend servers and Fastly #42
• Redirect former docs.webpaltform.org/w/img/ to www
• Redirect what had been served from static.webplatform.org to www
• Ensure gzip is enabled edge to client but not origin to Fastly. At least for wiki, so ESI will work
