v3.1.0

• Significant performance improvements (#74)
  • Prefetch endpoints in parallel when calculating the canonical endpoint
  • Redirects to other domain endpoints now return the cached endpoint object
  • Calls to the root of an endpoint now have an explicit trailing slash to facilitate caching and prevent a potential redirect depending on the domain configuration
  • resolves_to now makes a head request, and returns the redirected endpoint if the endpoint returns a non-30x response code, increasing the likelihood of a cache hit on internal redirects
  • Make checks threadsafe, parallelize checks (#70)
  • Default to HEAD requests for when we don't need the response body (#73)
• ColdFusion detection (#67)
• Ability to programmatically enable/disable checks (#62)
• Return error when domain points to localhost (#69)
• Added debug mode via DEBUG ENV var which forces Ethon and Typhoeus into verbose mode
