9 Proxying Requests to Another HTTP Server
9-2 Administration Guide
If you want to proxy requests to a cluster of WebLogic Servers, you can use the
HttpClusterServlet. For more information, see “Proxying Requests to a WebLogic
Cluster” on page 10-1.
New Version of the HttpProxyServlet
Service Pack 2 for WebLogic Server 6.1, contains a new version of the
HttpProxyServlet. The older version of HttpProxyServlet is still available and
functions as described in this document. Differences between the older version and the
new version are noted where appropriate in this document. The older version is
deprecated and will be removed from a future release.
The new version 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 Has a new Java package name. The full class name is now:
weblogic.servlet.proxy.HttpProxyServlet.
Setting Up a Proxy to a Secondary HTTP
Server
To set up a proxy to a secondary HTTP server:
1. Register the
proxy servlet in your Web Application deployment descriptor. The
Web Application must be the default Web Application of the Server that is
responding to requests.
