Web Tier Performance

When a SiteMinder Web Agent intercepts a request sent to a Web Server, the Web Agent makes the following calls to the SiteMinder Policy Server:

• isProtected
• isAuthenticated
• isAuthorized

• Change the timeout interval for Policy Server requests.
• Change the number of sockets that are available for a Web Agent to use for Policy Server connections.
• Use the Web Agent caches to reduce the number of calls a Web Agent makes to the Policy Server.
