The Application Server's Personal Security Environments
The information that the application server needs to communicate using SSL is stored in the server's Personal Security Environment (PSE). Because the information needed is different depending on whether the application server is the server or the client component for the communication, the server possesses multiple PSEs as follows:
The SAP Web Application Server uses this PSE when the application server is the server component for the communication, for example, when a user accesses the SAP Web Application Server using a Web browser.
The SAP Web Application Server uses one of the SSL client PSEs when the application server is the client component for the communication. The server can also use multiple SSL client PSEs, for example, it can use an anonymous PSE to access Web services that do not require client authentication and a different PSE to access services that do.
These PSEs are described in more detail in the topics that follow.
