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.
The proxy server for WebSphere Application
Server requires that you install the V6.0.2 update. Additionally, you must
augment the profiles that are associated with the deployment manager and the
nodes that are expected to host the proxy server 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.
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 to update the deployment
manager profile. The augmentProxyServer script that is provided with WebSphere
Application Server must be run on the deployment manager as well as all nodes
that host a proxy server. If you need to remove the feature from your deployment,
you can unaugment the proxy server feature from the profiles that are previously
augmented. Unaugmenting also removes any proxy servers that are configured
in the cell. You must stop the deployment manager prior to unaugmentation.
To augment or unaugment an existing profile, use the following scripts from
the bin directory of WebSphere Application Server.
You can uninstall
the proxy server by uninstalling the V6.0.2 updates. Any features that you
apply to deployment manager profiles using augmentation, after the update
is installed on the node, have to be unaugmented prior to uninstalling the
update on the node.
