Chapter 4 Configuring the Appliance 43
Setting server accelerator options
The Server Accelerator section allows you to configure the appliance as a
Server Accelerator (also known as a reverse or server-side proxy). You can enable
or disable this function as well as control how the appliance routes document
requests to the slower traditional Web servers. For more information about setting
up the appliance as a Server Accelerator, see Setting general controls‚ on
page 62.
The following table describes Server Accelerator options.
▼ Creating a document route rewriting rule
1 In the Server Accelerator section, click the Document Route Rewriting
Rules link.
The Configure: Routing: URL Rewriting page appears. This page displays
the set of current rules as well as a Add Entry button that lets you create new
rules.
Option Description
Server
Acceleration
Enables or disables server acceleration.
If you select on, the appliance is a server accelerator for the
Web servers specified in document route rewrite rules
defined through the command-line interface.
Reverse proxy
only
Sets the appliance to operate solely as a server
accelerator. If you select Yes, the appliance does not serve
requests to unspecified Web servers from the cache. See
Understanding server acceleration mapping rules‚ on
page 132 for information on creating document route
rewriting rules.
If you select No, the appliance serves requests from
unspecified Web servers as a normal proxy cache.
Document Route
Rewriting Rules
Allows you to view, modify, or add document route rewrite
rules. See Understanding server acceleration mapping
rules‚ on page 132 for information on document route
rewrite rules.
URL to redirect
requests without
Host header
Specifies an alternate URL that incoming requests from
older clients that do not provide a Host: header can be
directed.
It is recommended that you set this option to a page that
explains the situation to the user and advises a browser
upgrade or provides a link directly to the origin server,
bypassing the appliance. Alternatively, you can specify a
map rule that maps requests without Host: headers to a
particular server.
