Tweaked websocket support at Heroku

[skyluc]

I received this change notification about the websocket support at Heroku. Having a quick look at the doc and the application, I don't really see anything new.

To be investigated.

WebSockets now supports Keep-Alive

As a means of improving the performance of applications using our WebSockets implementation, Heroku has updated the way that the platform's routing architecture handles HTTP Keep-Alive. With Keep-Alive now enabled at the routing tier, applications can expect robust and normalized performance for both WebSockets and regular HTTP traffic.

Enabling this was a non-trivial engineering effort, due to the interplay between our load balancers, routing mesh, and dyno fleets. The new routing system is now in a well-tested and stable state, and we are giving more applications access to the new and improved router.

Your application, scala-ide-dashboard, will be on the new WebSockets and Keep-Alive router as of 03.26.14.

The documentation for the updated router can be found here: https://devcenter.heroku.com/articles/heroku-labs-router.

If you have any feedback or concerns, please let us know at rand@heroku.com.

Thank you!
