Adapt Hipache to work with OpenRuko

[Filirom1]

This is an old topic:

We have started it :
https://github.com/Filirom1/apiserver/commits/hipache
https://github.com/Filirom1/hipache/commits/openruko

And I dont' know if it's a good idea.

httprouting and Hipache use node-http-proxy opensourced by the PaaS company : nodejitsu.

Hipache depends on Redis, which is a great tool with a small footprint. But it's one more component to install. Heroku/Logplex too depends on Redis: openruko/logplex#4

If a compare Hipache with httprouting :

• Load-balancing across multiple backends : OK with httprouting
• dead-backend-detection but now it's easy with node-http-proxy to react on a bad dyno response : http-party/node-http-proxy@3b86a7a. And this job is done by rukorun and the heartbeat
• Multi-process architecture : done in 5min with cluster-master
• Memory monitoring : ouch this a nodejs problem or a node-http-proxy problem. BTW cluster-master could restart node gracefully periodically. That solve the problem
• Dynamic configuration : configuration is read in PostgreSQL instead of Redis
• WebSocket : done
• SSL : slow in nodejs SSL termination #9
• Custom HTML error pages : interesting but would it works in the Heroku way : Custom HTML error pages #11
• Wildcard domains support : Good : Custom domains #10

And I would like to add performance #8

Moreover there is a lot of features to be implemented to become a true clone of Heroku, that are not in Hipache. I fear that it will be harder to implement in Hipache than in httprouting.
