Cisco Cisco Content Acquirer Application

Release 2.5.7 of the Cisco Internet Streamer CDS introduces the following features:

In Release 2.5.7, the Web Engine has been enhanced and supports the following:

Optimization for small content objects

Optimization of Adaptive Bitrate Streaming for Move, Apple iPhone, and Smooth HD

Move VOD streaming

Move live streaming

MP3 live streaming

Cache on abort (content is cached if client request is aborted)

Maximum concurrent connections is 30,000. Alarm is raised and CDSM and SR are informed when 
an SE reaches 29,000 connections, allowing time for the SR to redirect requests to other SEs

The Web Engine in Release 2.5.7 interoperates with Apple’s media stream segmenter, as well as 
Microsoft’s Internet Information Services 7.0 (IIS7.0) Smooth Streaming. Apple’s media stream 
segmenter segments encoded media into separate files for streaming to iPhones. Microsoft’s IIS Smooth 
Streaming offers adaptive streaming of high-definition (HD) content.

The new Web Engine does not support IP-based redirection, an SR routing method. The new Web Engine 
follows the RFC 2616 standard with regards to caching content; therefore a number of the configuration 
settings have been removed in Release 2.5.7.

The following features are not supported in the New Web Engine:

IP-based redirection 

Syslog or alarm is not generated when number of concurrent sessions threshold is crossed

PCMM and ICAP

Outgoing proxy 

Maximum object size 

Cache on abort

Cache cookie

CLI commands:

http cache-cookies

http cache-on-abort

http reval-each-request all

http object max-size maxsize
