Network Deployment (Distributed operating systems), v8.0 > Set up intermediary services


Set up the proxy server

A proxy server is a specific type of application server that routes HTTP requests to content servers that perform the work. We can classify a proxy server according to the role that it plays in a system. This specific proxy server is classified as a reverse proxy server because the main function is to act as the first point of contact, not including the firewall, for client requests into the enterprise server. By contrast, a forward proxy server acts as the first point of contact for outbound traffic.

Review the topic that describes how to select a front end for your WAS topology. This topic helps you determine whether you should set up a web server plug-in, a proxy server, or a secure proxy server to provide session affinity, failover support, and workload balancing for your WAS topology.

If you are familiar with the functionality of the legacy proxy server that existed in versions of the product prior to v6.0, review the following list of functions that were available in the legacy proxy server but are not available in the current proxy server:

The proxy server acts as a surrogate for content servers within the enterprise. As a surrogate, you can configure the proxy server with rules to route to and load balance the clusters of content servers. The proxy server is also capable of securing the transport, using SSL, and the content using various authentication and authorization schemes. Another important feature is its capability to protect the identity of the content servers from the web clients by using response transformations (URL rewriting). The proxy server can also improve performance by caching content locally and by protecting the content servers from surges in traffic.

A proxy server configuration provides settings that control how a proxy server can provide services for the enterprise applications and their components. This section describes how to create and configure proxy servers in an existing application server environment.

In v6.0.2 of the product, you had to augment the dmgr profile to manage the proxy server. For Version 6.1 and higher, the proxy server is managed from the administrative console without initial augmentation.
