The EAServer application server hosts Web applications, and functions as a Web server. The redirector plug-ins are installed on third-party Web servers, and redirect requests to EAServer (for example, Apache to EAServer). You can also use redirectors to perform load balancing and failover. 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.
You can establish HTTPS (HTTP over SSL) connections between your Web server redirector and EAServer. This provides an SSL communication link (data integrity and encryption services), but does not support authentication services using client-side certificates.
Table 4-1 describes the Web servers for which a redirector plug-in is available, and the EAServer files required to enable them.When setting up a redirector for a specific Web server, simply unzip the appropriate redirector JAR file and the redirector-common-files.jar into the appropriate location for that Web server.
