Imaging Server Cache and Proxy
FSI Cache is a web application designed to run in a Java servlet container. Its primary aim is to serve as a cache for one or more imaging servers. Imaging servers like the FSI Server are optimized for processing image data and therefore generating content. They have hardware and system requirements quite different to those of a server meant for delivering content. In high performance environments with heavy traffic load on the servers, content delivery consumes immense system resources reducing image processing performance.

  In scenarios like this a cache is the best way to handle increasing traffic and optimize website performance.

FSI Cache is especially designed and optimized to cache the contents of imaging servers. Regardless of the type of service you are offering, classic single source imaging or zoomable high resolution images using FSI Viewer, FSI Cache will reduce the load on your imaging server and increase your websites performance.

The Basic Edition provides all features neccessary to increase website performance and reduce imaging server load in small to medium sized environments. It is the ideal extension to the FSI Server for classic single source imaging or dynamic imaging solutions using FSI Viewer.   The Enterprise Edition is designed for medium to large businesses with high-traffic websites.
