Web Server: Cognos 10 GatewaysThe Cognos 10 Web server tier contains one or more Cognos 10 gateways.Web communication in Cognos 10 is typically through gateways, which reside on one or more Web servers. A gateway is an extension of a Web server program that transfers information from the Web server to another server.When a Cognos 10 gateway receives a request, it• encrypts passwords to ensure security• extracts information needed to submit the request to a Cognos 10 server• attaches environment variables for the Web server• adds a default namespace to the request to ensure that the server authenticates the user in the correct namespace• passes requests to a Cognos 10 dispatcher for processing
