Reporter: Andy Wenk
[15:14:21] <yawnt> hi
[15:14:36] <yawnt> is it possible to cache couchdb using, for instance,
varnish and etags?
[15:14:44] <yawnt> all i can find on google is stuff that dates back 3
years :\
[15:15:33] <+rnewson> yawnt: yes, we send ETag, etc.
[15:15:47] <yawnt> because i read that varnish only supported etags in
the frontend
[15:15:52] <+rnewson> not much value in a cache for some operations, though.
[15:15:54] <yawnt> and doesn't check in the backend
[15:16:15] <yawnt> rnewson: in particular i'm talking about caching
attachments
[15:16:28] <+rnewson> competent http caching proxies will work in front of
couchdb, I don't know varnish.
[15:16:41] <+rnewson> caching attachments could be useful, sure.
[15:16:44] <+rnewson> and view output
[15:17:03] <yawnt> i guess i'll drop by in #varnish then
[15:17:05] <+rnewson> anywhere where the staleness check is cheaper than the
evaluation, basically.
[15:17:05] <yawnt> thanks for your help :)
[15:17:11] <yawnt> obviously!
[15:17:29] <+rnewson> I wish it were obvious to more people, :)
[15:17:51] <yawnt> haha yeah i suppose so
[15:18:51] <yawnt> cache isn't dark magic :D
[15:20:12] <+awenkhh> rnewson: maybe we could add some info about that in
the docu although it's already an existing concept hwen using http?
[15:21:34] <+rnewson> awenkhh: I guess we could expand on it, but, yeah,
it's a standard 2616 thing.
[15:22:16] <+awenkhh> rnewson: got an idea where a good place would be in
the docs?
[15:22:34] <+rnewson> none, sorry. I'm an avoider of documentation.
[15:22:35] <+Kxepal> awenkhh:
http://docs.couchdb.org/en/latest/config/proxying.html
[15:23:07] <+Kxepal> thought it contains information how to use couchdb as
proxy, I think it's good place about how to use proxies with couchdb too
