Enhancements and changes implemented in v5.0 Edge Component's Caching Proxy
 Technote (troubleshooting)
 
Problem(Abstract)
This document contains an overview of enhancements and changes introduced with version 5.0 for Edge Component's Caching Proxy.
 
Resolving the problem
New features introduced with Edge Component's Caching Proxy, version 5.0:
  • Enhanced log support (MaxLogFileSize)
    This feature allows the proxy to record logging entries to a sequence of log files.
  • JunctionRewrite for reverse proxy
    This feature helps improve the proxy interface to multiple backend servers through a directory layer inserted for all HTMLpages proxied by Edge Component. Backend servers need minimal changes to implement this feature. The proxy rewritew the pages, or inserts a proxy cookie, and with subsequent incoming requests, maps requests to the correct servers.
  • VirtualHost support based on IP address and port
    This feature allows virtualhost to work on the same machine with different IP addresses or ports.
  • Server-side connection management (Linux only)
    This feature allows the proxy to maintain server-side connections and as a result, to achieve better performance. The working threads do not block on server-side sockets, and serve other requests when the response is not quickly available.
  • Caching enhancements
    Various proxy-caching improvements, such as one GC thread per device, have been implemented.
  • Code and documentation corrections are integrated into the V5.0 release.

Features removed from Edge Component, version 5.0:
  • Content Distribution
  • Trigger Monitor
  • Application Offload
  • Cyber Patrol filtering plug-in
  • Transactional Quality of Service (TQoS) plug-in
