Remi Tricot-Le Breton 6cb10384a3 MEDIUM: cache: Add support for 'If-None-Match' request header ... Partial support of conditional HTTP requests. This commit adds the support of the 'If-None-Match' header (see RFC 7232#3.2). When a client specifies a list of ETags through one or more 'If-None-Match' headers, they are all compared to the one that might have been stored in the corresponding http cache entry until one of them matches. If a match happens, a specific "304 Not Modified" response is sent instead of the cached data. This response has all the stored headers but no other data (see RFC 7232#4.1). Otherwise, the whole cached data is sent. Although unlikely in a GET/HEAD request, the "If-None-Match: *" syntax is valid and also receives a "304 Not Modified" response (RFC 7434#4.3.2). This resolves a part of GitHub issue #821.		2020-10-22 16:10:20 +02:00
