I wasn't necessarily saying you should take a dependency on it. http://ayende.com/4748/ravendb-http-caching#comment16http://ayende.com/4748/ravendb-http-caching#comment16Wed, 12 Jan 2011 10:10:34 GMTGlenn, Take a look at how this implemented in RavenDB: [github.com/.../HttpJsonRequest.cs](https://github.com/ayende/ravendb/blob/master/Raven.Client.Lightweight/Client/HttpJsonRequest.cs) Maybe 20 lines of code, and it works. No configuration, no need to understand an extensibility mechanism. http://ayende.com/4748/ravendb-http-caching#comment15http://ayende.com/4748/ravendb-http-caching#comment15Wed, 12 Jan 2011 10:07:44 GMTCassio, I have a working version, one that supports ETags and caching and everything. It is not a burden to maintain, so I think I'll not use it. http://ayende.com/4748/ravendb-http-caching#comment14http://ayende.com/4748/ravendb-http-caching#comment14Wed, 12 Jan 2011 09:12:01 GMTGlenn is working on this project wcf.codeplex.com His blog - [http://codebetter.com/glennblock/](http://codebetter.com/glennblock/) But I'm pretty sure ETag is not implemented It is in preview version and lacks docs, but is open source. You can digest it in one morning. :) http://ayende.com/4748/ravendb-http-caching#comment13http://ayende.com/4748/ravendb-http-caching#comment13Wed, 12 Jan 2011 08:52:31 GMTCassio, no, just standard http call from .NET http://ayende.com/4748/ravendb-http-caching#comment12http://ayende.com/4748/ravendb-http-caching#comment12Wed, 12 Jan 2011 07:59:54 GMTStephane, Can you send me a link to this? http://ayende.com/4748/ravendb-http-caching#comment11http://ayende.com/4748/ravendb-http-caching#comment11Wed, 12 Jan 2011 07:59:31 GMTAyende, are you using any third party API to implement REST and JSON serialization? Like stephane said, Glenn Block is ahead of a project to support REST over WCF. There is OpenRasta too but I would like to hear more opinions. I know that WCF REST doesn't support ETag yet but will in future. Probably OpenRasta already support it. http://ayende.com/4748/ravendb-http-caching#comment10http://ayende.com/4748/ravendb-http-caching#comment10Wed, 12 Jan 2011 01:20:19 GMTha, I was at a .NET user group session by Glenn Block about the next WCF api for http endpoint where he explain exactly that. Wouldn't it be possible to use it? It is available on codeplex I think. http://ayende.com/4748/ravendb-http-caching#comment9http://ayende.com/4748/ravendb-http-caching#comment9Tue, 11 Jan 2011 21:43:59 GMTYuriy, Internally this is a MemoryCache with the name: "Raven.Client.Client.HttpJsonRequest.Cache" You can configure this any way you want. http://ayende.com/4748/ravendb-http-caching#comment8http://ayende.com/4748/ravendb-http-caching#comment8Tue, 11 Jan 2011 15:45:49 GMTYep Oren, welcome to The Internet ;-) , a place that is essentially a Representational Resource State Transporation System.

Where is the client cache stored? Is it in the DocumentSession object, DocumentStore, or somewhere else? I ask because in a web application the DocumentSession will likely be created and destroyed per request, making the cache not too useful, unless it's a static property of the session that sticks around. http://ayende.com/4748/ravendb-http-caching#comment3http://ayende.com/4748/ravendb-http-caching#comment3Tue, 11 Jan 2011 14:41:24 GMTJason, Yep, pretty much http://ayende.com/4748/ravendb-http-caching#comment2http://ayende.com/4748/ravendb-http-caching#comment2Tue, 11 Jan 2011 14:40:23 GMTSo, http (2nd level) cache is on by default, just update the client and server binaries? That is frictionless :) http://ayende.com/4748/ravendb-http-caching#comment1http://ayende.com/4748/ravendb-http-caching#comment1Tue, 11 Jan 2011 14:37:14 GMT
