Title: Message Title

beliys created an issue   Puppet / PUP-9971 Add ETag support to the source attribute of the file resource type for http Issue Type: New Feature Assignee: Unassigned Created: 2019/08/21 3:57 AM Priority: Normal Reporter: beliys Now according to the documentation: The http source uses the server Content-MD5 header as a checksum to determine if the remote file has changed. If the server response does not include that header, Puppet defaults to using the Last-Modified header. But github does not use any of these headers, and it would be nice to check the ETag header for efficient file downloads from there. An example of the current headers for a file with github: curl -I https://raw.githubusercontent.com/major/MySQLTuner-perl/master/mysqltuner.pl HTTP/1.1 200 OK Content-Security-Policy: default-src 'none'; style-src 'unsafe-inline'; sandbox Strict-Transport-Security: max-age=31536000 X-Content-Type-Options: nosniff X-Frame-Options: deny X-XSS-Protection: 1; mode=block ETag: "fe63f5cd29814a03d94e68e5f503e2b0b6d65bfe" Content-Type: text/plain; charset=utf-8 Cache-Control: max-age=300 X-Geo-Block-List: X-GitHub-Request-Id: E292:4560:96247:C7C3E:5D5D220C Content-Length: 221615 Accept-Ranges: bytes Date: Wed, 21 Aug 2019 10:54:49 GMT Via: 1.1 varnish Connection: keep-alive X-Served-By: cache-ams21025-AMS X-Cache: HIT X-Cache-Hits: 1 X-Timer: S1566384890.584825,VS0,VE1 Vary: Authorization,Accept-Encoding Access-Control-Allow-Origin: * X-Fastly-Request-ID: 837bdb865032ad409e8685b36f6ccfa87832832e Expires: Wed, 21 Aug 2019 10:59:49 GMT Source-Age: 236 Add Comment   This message was sent by Atlassian JIRA (v7.7.1#77002-sha1:e75ca93) -- You received this message because you are subscribed to the Google Groups "Puppet Bugs" group.
