The remote user makes a request to the proxy, the proxy acts as a go-between and obtains the information from the internal web server, and then the proxy returns the result to the remote user. For example, when an external user with a Web browser tries to access the company’s internal web server, the application gateway runs a proxy application that simulates the internal web server.Ī session is established between the remote user and the proxy application, while a separate, independent session is established between the proxy application and the internal web server.
Application gateways examine incoming packets at the application level and use proxies to create secure sessions with remote users.
