Proxy Server can help relieve bandwidth congestion at network bottlenecks and ensure that users are securely and productively accessing network resources. Reduce network traffic on your intranet and improve response times for users. Proxy Server caches frequently accessed documents automatically and requests data from its source only when that source has been updated or has expired, which reduces network traffic and gives users access to fresh content without the wait. Documents or entire sites can be preloaded into the cache, and administrators can schedule updates of cached content. Whole sites can be downloaded during low-traffic periods, for example, so they're fresh when users need them.
Organizations can configure arrays of proxies for better scalability and reliability.
Proxy arrays enable distributed caching for efficient load balancing and fault tolerance. Support for dynamic proxy routing also lets Proxy Server query other caches for document availability. Increase network security and user productivity by filtering content and controlling both internal and external access to information. Proxy Server lets administrators limit access to objectionable content at the Internet gateway by filtering URLs, content such as viruses and HTML tags, and content types such as ActiveX. Administrators can also control user and group access to specific documents or sites. Reverse proxying lets Proxy Server cache documents outside the firewall for outsiders who request internal company documents.
