Platform Improvements

Testing SEO Now Supported on Platform Domains

Site Auditor (aka RavenCrawler) can now access platform domains to support pre-release SEO testing. Please contact support if you would like to see other tools given this access.

OCSP Stapling Enabled on Global CDN

OCSP stapling is an improved method for quickly and safely checking the validity of certificates for HTTPS. You can use SSL Labs (e.g. https://www.ssllabs.com/ssltest/analyze.html?d=pantheon.io) and search for "stapling" to see it's enabled. OCSP responses are typically good for about 7 days, so a response will only get updated as its validity lifetime expiration time approaches.

Global CDN Surrogate-Key-Raw Disabled by Default

The Surrogate-Key-Raw header, used for debugging when using Pantheon Advanced Page Cache, is no longer sent by default. To receive this header when making a request, send the Pantheon-Debug: 1 header, like so:

curl -IsH "Pantheon-Debug:1" https://example.com | grep key

This change addressed an issue that caused Twitter card validation to fail, and also reduces overall page size and speeds up page load time when sending many keys.
