Chapter 9 Web Server Redirector Plug-In

Configuring EAServer to accept Web server requests

This section lists the steps you must perform in your EAServer installation so that it accepts requests from the Web server.

Setting the EAServer HTTP listener properties

The HTTP listener properties that are related to the Web server redirector plug-in are defined in the listener properties file for each EAServer HTTP listener that receives Web server requests:

com.sybase.jaguar.listener.http.connector_events - this is a required property and must be set to true so that the listener can properly process requests from the Web server.
WARNING!
If you do not set the com.sybase.jaguar.listener.http.connector_events property to true, some of the redirector's features, such as load balancing, may not work correctly.
com.sybase.jaguar.listener.http.conn.keepalive - this is an optional property that specifies the length of time, in seconds, to keep a connection alive before it is closed by EAServer. The default value is 120 seconds (2 minutes) and can be modified, if necessary, to improve performance.
com.sybase.jaguar.listener.http.conn.maxrequests - this optional property determines the number of requests processed before EAServer closes the connection. The default value is 100 and can be modified, if necessary, to improve performance.

The listener properties files are located in the JAGUAR_HOME/Repository/Listener directory. The file name format is <servername>_<listenername>.props. For example, the listener property file name for a listener named "http1" created for a server named "Jaguar" is Jaguar_http1.props.

Use a text editor to add the following lines to each listener properties file that accepts requests:

com.sybase.jaguar.listener.http.conn.keepalive=120

com.sybase.jaguar.listener.http.conn.maxrequests=100

com.sybase.jaguar.listener.http.connector_events=true

EAServer host and port settings

You must make sure the EAServer host and port defined in your redirector configuration file has an identical host name in the EAServer listener host and port fields. For example, this redirector entry also requires an EAServer HTTP protocol listener defined with the host name of jaghost1 and a port number of 8080:

Connector.WebApp /*=http://jaghost1:8080

jaghost1 is not equivalent to jaghost.domain, where domain is the domain in which EAServer is hosted.
