Hi,

I implemented proxy server for Elastic Search in Node. It can be found  
here: [http://github.com/lukas-vlcek/node.es](http://github.com/lukas-vlcek/node.es)  
Basically it provides the following for you:

1. It can restrict access to Elastic Search HTTP REST API (by default it  
exposes _safe_ operations only).
2. You can provide handlers to modify HTTP client request (e.g. you can  
ensure that size is not too big) and Elastic Search response (e.g. you can  
remove sensitive data).
3. It round-robin client requests among active HTTP enabled nodes (it  
periodically refreshes list of active nodes), thus, it can provide a single  
URL for clients to communicate with Elastic Search cluster.

More detailed documentation can be found in the source code:

> <https://github.com/lukas-vlcek/node.es/blob/master/proxy/elasticsearch-proxy.js>

  
The code is still quite new and a bit sketchy at some parts but I would love  
to get some feedback.

Regards,  
Lukas

This looks great lukas!, hopefully this will also be the home for a node.js  
client for elasticsearch.
