Proxy servers in distributed heterogeneous multi-network environments

Methods of organization of information interaction in the distributed systems, based on the proxy-servers technology are considered. The key areas of the technology application in development of systems on the basis of Web technology and .NET architecture are described. Examples of proxy-servers technology application for solution of problems like supervision and monitoring of queries to Web-sites, interactions support between remote private networks and protection of SOAP messages in information queries are given.
