Microsoft Internet Information Services (IIS)

When Easit GO is installed in a Windows environment "IIS" is used as a frontend for Easit GO. It is configured to handle incoming traffic on port 443 and redirect that traffic to Easit GO, running an embedded Tomcat server.

IIS can also be configured to handle "SSO" if the user should be authenticated against Active Directory. If you chose this SSO-option, the IIS server will forward user identity in a header to the Tomcat service. Please note that securing the Tomcat service in this case is very important, so that no unauthorized services can send request to the Tomcat server.

Each instance of Easit GO on the server have one or more application pool(s) and site(s) configured in IIS.

Since IIS normally can not execute Servlets and Java Server Pages (JSPs), each site has a ISAPI filter configured using the ISAPI redirector plugin and that will let IIS send servlet and JSP requests to Tomcat (and this way, serve them to clients).

The ISAPI redirector plugin in turn is configured to communicate with Easit GO using the AJP connector.
