20:45 saml hello web scalers
20:46 saml GET /foo      is proxy of /bar.   how do I implement this? 3xx?   API contract is GET /foo to return 200 Ok with same representation of /bar
20:46 saml so, I want to avoid 3xx if possible
22:24 whartung not sure if I understand completely saml
22:28 impl saml: you can add a HTTP Link header? Link: <http://yourapi/bar>; rel="canonical"
22:32 whartung what are the semantics of hte link header?
22:34 impl https://tools.ietf.org/html/rfc8288#section-2
22:35 impl it's basically the same as the HTML <link> tag
22:36 whartung do you think that manifests as a proxy, as saml mentioned originally?
22:36 whartung My question is what he means by “proxy”
22:37 impl yeah - i assumed he didn't mean a literal reverse proxy but rather returned the same content at an alternate URI
22:37 whartung that’s the way I interpret it, and in that case the 3xx doesn’t really apply (as 3xx is not the “same content”)
22:37 whartung IMHO
22:38 impl yeah, i would return 200 with the Link header
22:38 Haudegen joined #rest
22:38 whartung I woul djust returnt the conent, I’d map the URL in the routing layer
22:38 saml i guess my actual question is if a resource has multiple urls, what do I do? redirect to canonical url?
22:39 saml or does it even matter?
22:39 whartung Yea, I think impls idea of returning the link header, but I’d also return the original content.
22:39 whartung depends on your motivation for the proxy — why is it there at all why does a resource have two names?
22:39 impl yeah - to be clear, I meant 200 with the content, and not e.g. 204 and only the link header.
22:40 saml let's say GET /foo  actually downloads something from S3 (amazon storage thingy)  and serves it
22:40 saml GET /foo    GET /bar   may download the same object from S3
22:40 whartung first, I as a client “don’t care” what you as a server do, right? How you’re sending me the content.
22:40 saml so, I was wondering if it's simpler just to have GET /foo redirect
22:41 whartung flat file, s3, db, etc.
22:41 saml right
22:41 whartung well the advantage of the redirect is that s3 is taking the bandwidth hit.
22:41 saml that's true
22:41 whartung and, it’s a good question abou tthe semantics of a temporary redirect
22:42 whartung if you use a temp redirect, you don’t “rename” the resource, per se, right?
22:42 whartung so I think that would be ok, actually.
22:42 whartung a permanent redirect I consider more of a “this name is wrong, use this new one"
22:42 saml hrm thanks. i'll think about this on the bus
22:47 whartung here ya go
22:47 whartung 10.3.6 305 Use Proxy
22:47 whartung The requested resource MUST be accessed through the proxy given by
22:47 whartung the Location field.
