Table 8-3 HttpClusterServlet Parameters

<param-name>	<param-value>	Default Value
defaultServers	(Required) A list of host names and port numbers of the servers to which you are proxying requests in the form: host1:HTTP_Port:HTTPS_Port| host2:HTTP_Port:HTTPS_Port (Where host1 and host2 are the host names of servers in the cluster, HTTP_Port is the port where the host is listening for HTTP requests, and HTTPS_Port is the port where the host is litening for HTTP SSL requests.) Separate each host with the | character. If you set the secureProxy parameter to ON (see the secureProxy entry) The HTTPS port uses SSL between the WebLogic Server running HttpClusterServlet and the WebLogic Servers in the cluster. You must always define an HTTPS port, even if you have set secureProxy to OFF.	None
secureProxy	ON/OFF. If set to ON, enables SSL between the HttpClusterServlet and the member of a WebLogic Server cluster.	OFF
DebugConfigInfo	ON/OFF. If set to on, you can query the HttpClusterServlet for debugging information by adding a request parameter of ?_WebLogicBridgeConfig to any request. For security reasons, it is recommended that you set this parameter to OFF in a production environment.	OFF
connectionTimeout	The amount of time, in seconds, that a socket waits in between reading chunks of data. If the timeout expires, a java.io.InterruptedIOException is thrown	0 = infinite timeout.
numOfRetries	Number of times HttpClusterServlet will attempt to retry a failed connection.	5
pathTrim	String to be trimmed from the beginning of the original URI.	None
trimExt	The file extension to be trimmed from the end of the URI.	None
pathPrepend	String to be prepended to the beginning of the original URL, after pathTrim has been trimmed, and before the request is forwarded to a WebLogic Server cluster member.	None
