Overview

The EAServer application server hosts Web applications, and functions as a Web server. The redirector plug-in is installed on the Web server host, which allows you to send client requests directly to the Web server. The Web server forwards requests that need to access EAServer servlets, JSPs, and so on, to EAServer. EAServer processes the requests and returns the results back to the Web server.

Beginning with EAServer version 4.1.3, you can establish HTTPS (HTTP over SSL) connections between your Web server redirector and EAServer. This provides an SSL communication link, including data integrity and encryption services, but does not support authentication services using client-side certificates.

The Web servers for which a redirector plug-in is available for HTTP and HTTPS connections are:
