Feature #14199
Updated by Tom Clegg over 5 years ago
API to instruct keepstore to fetch a remote block, save it, and return signed locator (variation on "proxy a block read request" with the added feature of saving the block). Proposed API: Request header Add "X-Keep-Signature: local, time=T" (where T is an RFC3339 timestamp) local" this implies the block should will be retained by keepstore. The response includes the header "X-Keep-Locator: abc+123+Aabc" The client will do Do a HEAD request (equivalent to the GET request) on remote signed locator and look for a response header that has a new locator with local block signature. All keepstore GET and HEAD responses for block requests should support this new header/response When the "X-Keep-Signature" request header "X-Keep-Signature: local" is provided, the timestamp on the underlying block must be updated before a new signature can be returned. Responses with an X-Keep-Locator header must also include a "Vary: X-Keep-Signature" header.
