Warp Solutions last week added to its SpiderCache suite of caching and acceleration products a reverse proxy tool that the company says can manage clusters of edge-based caching servers and improve application delivery to Internet users, remote sites and branch offices.SpiderCache Reverse Proxy (RP) is a software-based appliance that can be part of a cluster of SpiderCaches (both locally and across an enterprise). When part of a cluster, SpiderCache RP can act as a parent and manage other SpiderCache RP and SpiderCache Node applications.A reverse proxy is a gateway for servers and enables one Web server to provide content from another transparently; a common reason to run a reverse proxy is to enable controlled access from the Web at large to servers behind a firewall. As with a standard proxy, a reverse proxy can improve performance. Reverse proxies can also be used for security purposes, to mask the Web servers behind the proxy server, and also for load balancing, to improve speed and performance.SpiderCache products use caching algorithms to store dynamically created pages and reduce the processing requirements on active servers by caching static, rich media and dynamic Web content.Warp says enterprise companies using SpiderCache RP can establish an application delivery network or an enterprise content delivery network. The company says the RP appliance will speed the delivery of dynamic Web content to branch offices by reducing latency, optimizing bandwidth consumption and speeding network traffic across WAN and Internet connections. The products also include partial-page caching, compression, and SSL offloading options to improve speed, Warp says.Available now, pricing for Warp SpiderCache RP starts at $7,000.
