  • Automatic retrieval of changed files by a network software agent
    Patent number: 6029175
    Abstract: An intelligent network agent intercepts transactions between clients and servers to perform Distributed Information Logistics Services (DILS) functions such as automatically retrieving updated files from remote servers and delivering them to local client programs. For example, HTTP clients and HTTPD servers are connectionless and stateless, thus there is no way for a server to update a browser automatically when an HTML document is changed. The invention provides a method to update any number of clients from any number of servers without making any changes to currently existing HTTP clients or HTTPD servers. Furthermore, the invention can provide various other DILS services for clients to reduce latency and communication costs for members of a group with interests in similar objects.
