Microsoft Application Request Routing (ARR) Version 2 for IIS7 Beta 1 has been released.

Overview:

ARR version 2 beta 1 is an incremental release that includes all of the features from version 1, and adds support for disk-based cache.

More specifically, ARR version 2 beta 1 can be used to:

· Enhance ARR version 1 scenarios with disk cache.

· Use ARR as a cache proxy as an edge cache in CDN/ECN environment.

Download ARRv2 beta 1 from:

· Microsoft Application Request Routing Version 2 for IIS7 Beta 1 (x86)

What’s new in ARRv2 beta 1:

· Disk-based caching

In addition to the kernel memory cache in ARR version 1, version 2 beta 1 adds support for disk-based cache.

· Cache proxy

Because ARR is a proxy-based HTTP request routing module, with support for disk cache, ARR can be used as a cache proxy as an edge cache.

· Cache hierarchy management

Define and manage relationships between cache nodes, including support for Cache Array Routing Protocol (CARP).

· Caching while serving response

Caching large content, such as a movie clip, may take some time. ARR version 2 beta 1 is capable of caching the content while serving the response immediately.

· Caching compressed objects

Disk-based cache stores compressed objects so that the objects do not have to be compressed in real time for every request.
