Access components provide front-end access to system services, often from Internet locations outside an enterprise firewall. The following Java ES access components are described in this section:
Sun Java System Portal Server Secure Remote Access (Portal Server Secure Remote Access) extends Portal Server by offering browser-based secure remote access to Portal Server content and services from any remote browser, eliminating the need for client software. Integration with Portal Server ensures that users receive secure access to the content and services that they have permission to access.
Portal Server Secure Remote Access includes the following subcomponents:
Portal Server Secure Remote Access Core. Provides core functionality.
Gateway. Provides the interface and security barrier between remote user sessions originating from the Internet and a corporate intranet. Gateway presents content securely from internal web servers and application servers through a single interface to a remote user and controls communication between the Portal Server and the various Gateway instances.
Netlet Proxy. Enables users to securely run common TCP/IP services over the Internet and other non-secure networks. Netlet allows you to run applications such as telnet, SMTP, HTTP, and fixed-port applications. Netlet enables remote access and operation of file systems and directories and ensures secure communication between the Netlet applet on the client browser, the Gateway, and the application servers.
Rewriter Proxy. Enables secure HTTP traffic between the Gateway and intranet computers. Rewriter provides secure access to corporate intranet web pages from outside of the intranet by transforming web links and creating rule sets for handling intranet web pages.
Sun Java System Web Proxy Server (Web Proxy Server) provides caching, filtering, and distribution of web content. Web Proxy Server is often used inside enterprise firewalls to reduce the number of requests to remote content servers, and outside firewalls to provide a secure gateway for incoming Internet requests.
The Java ES installer provides Web Proxy Server as a single installable component.
