Setting up the proxy server

The proxy server is a specific type of application server that routes HTTP requests to content servers that perform the work. The proxy server is the initial point of entry, after the firewall, for requests into the enterprise.

Why and when to perform this task

[Version 6.0.2]The proxy server for WebSphere Application Server requires that you install the V6.0.2 update. Additionally, the profiles that are associated with the deployment manager and the nodes that are expected to host the proxy server need to be augmented to contain the artifacts that you need to administer and manage the proxy server feature.

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 Secure Sockets Layer (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. The proxy server is available in the WebSphere Application Server Network Deployment V6.0.2 offering and higher.

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.

[Version 6.0.2]Augmentation of the deployment manager profile enables the management of the proxy server feature in the administrative console. You must stop the deployment manager prior to augmentation in order to update to the deployment manager profile. The augmentProxyServer script that is provided with WebSphere Application Server must be run on the dmgr as well as all nodes that will host a proxy server. If the feature needs to be removed from your deployment, you can unaugment the proxy server feature from the profiles that were previously augmented. Unaugmenting will also remove any proxy servers that are configured in the cell. The deployment manager needs to be stopped prior to unaugmentation. To augment or unaugment an existing profile, use the following scripts from the bin directory of WebSphere Application Server.

[Version 6.0.2]

Steps for this task

What to do next

Next, create proxy servers in the cell.

[Version 6.0.2]You can uninstall the proxy server by uninstalling the V6.0.2 updates. Any features that you applied to deployment manager profiles, using augmentation, after the update was installed on the node, will have to be unaugmented prior to uninstalling the update on the node.
