v1.07

• Bugfix: Don't install ESI scan filter when there is no body, as this will trip up the gunzip filter.

v1.06

Bugfix: Gunzip filter needs to pass the buffer size through to final reader() call

v1.05

• Bugfix: Error logging in sort_byte_ranges used wrong constant (thanks @tomdmaguire)
• Bugfix: Fixed redis auth (thanks @tomdmaguire)
• Bugfix: ESI fragments no longer use parent request method and headers. Instead, only a subset are passed through and GET is always issued.
• Feature: Added a new event before_request which is passed the upstream request parameters allowing for last minute manipulation (thanks @forkfork)
• Feature: Internal gunzip support (thanks @hamishforbes)
• Feature: ESI fragments now include an X-ESI-Parent-Request request header.

v1.04

• BUGFIX: ssl_handshake was not being called for ESI fragments over https

v1.03

*Optimistically try to clean up when data structure looks bad during "delete".

v1.02

• Better error logging in the cache body writer (thanks @hamishforbes)
• Broken entities (e.g. some keys missing under memory pressure) are now cleaned up on discovery.
• Bugfix: Zero length bodies were no longer being cached.
• Bugfix: Responses which have become non cacheable would cause an immediate delete, even though concurrent requests may be reading from them. Entity deletion is now deferred to garbage collection instead.

v1.01

• Feature: Added full streaming ESI 1.0 support including conditionals. A few not-very-useful exceptions are documented.
• ESI processing now depends on Surrogate-Control / Surrogate-Capability headers, which in the past were not required.
• Feature: Wildcard PURGE requests, e.g. PURGE /news/* HTTP/1.1
• Moved Redis connections to use lua-resty-redis-connector.
• Numerous bug fixes and improved test cases around entity garbage collection.
• Test suite now reports on Qless job errors.

v0.16

Bugfix: Removed untracked uris_by_expiry set which will bloat over time.

v0.15

Fixed issue where status code defaulted to 200 when response body is missing.

v0.14

• Adds support for relative URIs in ESI includes. These are resolved to the current URI.
