<roidrage> anyone ever put a reverse proxy in front of riak? 

<technoweenie> some people in a HN thread mentioned throwing nginx in front 
of it for auth purposes 

<guestuser> i currently am transferring data from tokyo to riak and am using 
a patched nginx to distribute writes 

<justinsheehy> I know of at least one Varnish-fronted instance. 
I don't have access to it so can't give details, but it exists. 

<copious> we use varnish to route PUT/GET requests for our data storage, 
VCL is extremely extensible for that type of thing. Easier to write that than to patch nginx. 

<roidrage> what does varnish cache on with riak? i've been wondering how to put a cache in 
front of couchdb and figured riak might have similar ways/problems/solutions. i'd expected 
to be able to cache on the etag but varnish doesn't seem to support that unfortunately, 
neither does nginx as it seems 

<enquora> roidrage: I've wondered the same thing, although it looks as though I can 
avoid a proxy completely now so it's become less of an issue. Can varnish not do this
 with VCL? 

<enquora> what I meant was, using an inline c function? 

<enquora> using it for his hosted couchdb operation 

<enquora> AFAIK 

<roidrage> hum, he didn't mention it when i brought it up over there. 

<roidrage> enquora: that depends on your viewpoint. varnish can handle clients with the 
etag, but not backends

<enquora> hmmm 

<roidrage> i don't know, haven't looked that deep into it, i was just mind-blown 
it's not possible yet 

<enquora> there's another reverse-proxy that kocolosk on #couchdb recommends, 
sorry, forgotten the name. Documentation is weird, but he swears by it. 

<enquora> using it for his hosted couchdb operation 

<enquora> AFAIK 

<roidrage> hum, he didn't mention it when i brought it up over there.

<drev1> roidrage: can you pass Etags through Varnish directly to Riak? 

<enquora> roidrage: I just asked him, but no response. I'll see if I can dig it up 
in my transcript logs. 

<roidrage> drev1: that i don't know. 

<roidrage> i was just curious if people have dealt with this kind of stuff. and 
was sort of disappointed today that varnish doesn't seem to handle backends based on etag 

<enquora> roidrage: it's HAProxy. http://haproxy.1wt.eu/ 

<seancribbs> HAProxy is just a reverse-proxy/load-balancer. it doesn't cache 

<roidrage> yeah  exactly. it's super-awesome though :) 

<seancribbs> indeed 

<enquora> this is why we're moving as quickly as possible to a no-middleware environment.
