10 Proxying Requests to a WebLogic Cluster
10-2 Administration Guide
New Version of the HttpClusterServlet
A new version of the HttpClusterServlet was introduced in WebLogic Server 6.1
SP02. The older version is still available, but it is deprecated and will be removed from
a future release. Differences between the older version and the new version are
described in this document.
The WebLogic Server 6.1 SP02
HttpClusterServlet has the following features:
n Supports HTTP 1.1, including chunk-transfer and keep-alive.
n Uses connection pooling to improve performance.
n Uses a new set of parameters to define functionality. These parameters are the
same as the parameters used for the Apache, Netscape, and Microsoft IIS
plug-ins packaged with WebLogic Server.
n Uses a new Java package name. The full class name is:
weblogic.servlet.proxy.HttpClusterServlet.
Setting Up the HttpClusterServlet
To use the HTTP Cluster Servlet, configure it as the default web application on your
proxy server machine, as described in the steps below. For an introduction to web
applications, see “Overview of Web Applications” in Assembling and Configuring
Web Applications.
1. If you have not already done so, configure a separate, non-clustered Managed
Server to host the HTTP Cluster Servlet.
2. If you have not already done so, create a directory for the web application, and a
WEB-INF subdirectory within the web application directory. For more
information, see “Directory Structure” in Assembling and Configuring Web
Applications.
