Mistserver – Optimize the HTTP delivery via caching

In the previous post, we looked the new features of MistServer (version 1.1).
varnishToday, I expose an idea exposed by a friend Nicolas Weil. We talked about the content caching for an architecture based on Mistserver especially for HTTP based format. We thought about Varnish, an HTTP accelerator. The idea is to keep in cache the different fragments which are generated by MistServer. This article will not talk about the RTMP or TS part, theses protocols are not HTTP based.

To make this test, I use on the same server MistServer and Varnish. Here is the architecture.

A new small blog post where I sticked informations or links about Rest and Restful :a style of architecture for distributed softwares. This post will be updated each time I have new links.

Restful is stateless. The main goals of Restful architecture are scalability, availability and agnotiscs technologies between software (via an common interface). A new Internet draft is out, it names RESTful Authentication Pattern and will help to design your architecture.

If you will deploy this type of architecture, you can read this slideshare which give best practices to design API (a webinar is available too). To design a Restful architecture, you need to design your URI. There is another good document made by Apigee : Web API Design – Crafting interfaces that Developers love [PDF file]

Here is some examples of API architectures:

To conclude, there is a tool to assist you on your development : Rest-client. It’s a Java app (so cross-platform) to test your Restful webservices.
