Content Engine GUI Tabs

Table A-1 describes the four feature tabs and their associated functions.

Table A-1 Content Engine GUI Feature Tabs 

Tab	Description
WCCP	Enables WCCP on the Content Engine and configures WCCP-related parameters and services (for example, configures the Content Engine to support the web cache service).
Caching	Configures cache-related parameters (for example, content preloading) on the Content Engine.
System	Configures system-related parameters (for example, access lists, DNS, and Websense server parameters) on the Content Engine.
Reporting	Displays statistics (for example, disk statistics, performance statistics, and WMT streaming statistics) gathered by the Content Engine. Displays a hardware profile (model number, CPU, memory, disks, SCSI, and NICs) of the Content Engine, and the version of the ACNS software that is currently running on the Content Engine.

WCCP Tab and Subtabs

Table A-2 lists the ACNS software, Release 5.1 or later features that can be configured from the WCCP tab and subtabs of the Content Engine GUI.

.

Table A-2 Content Engine GUI WCCP Subtabs 

Subtab Option	Description
Enable WCCP	Enables WCCP on the Content Engine. Use to enable WCCP Version 1 or WCCP Version 2 on the Content Engine.
Clustering	Sets parameters related to WCCP service clusters.
Custom Web Cache	(For WCCP Version 2 configuration only) Configures the WCCP custom web cache service on the Content Engine. When the Content Engine is configured to support this WCCP Version 2 service, it acts as a transparent forward proxy server for HTTP requests that are transparently redirected to it by any of the WCCP-enabled routers on the specified router list. If the requested content is not it its local cache, the Content Engine retrieves it from the origin web server, stores a local copy for future requests, and sends the client the requested content. Subsequent requests for the same content is served from the local cache on the Content Engine.
Reverse Proxy	(For WCCP Version 2 configuration only) Configures the WCCP reverse proxy service on the Content Engine. When the Content Engine is configured to support this WCCP Version 2 service, it acts as a reverse proxy; the Content Engine acts as a proxy on behalf of the origin web server.
RTSP	(For WCCP Version 2 configuration only) Configures the WCCP RTSP media cache service on the Content Engine (a transparent forward proxy server). The Content Engine listens for redirected RTSP requests on the standard RTSP port (default port 554). To configure the Content Engine to listen for intercepted RTSP requests on ports other than the default port (port 554), configure a user-defined WCCP service (services 90-97). If the requested content is not it its local cache, the Content Engine retrieves it from the origin streaming server, stores a local copy for future requests, and sends the client the requested content. Subsequent requests for the same RTSP streaming content is served from the local cache on the Content Engine.
Services	(For WCCP Version 2 configuration only) Configures the Content Engine to cache web traffic using multiple ports, using the user-defined WCCP services (service 90 to 97). To configure these generic WCCP Version 2 services, use this WCCP Services window.
Web Cache	(WCCP Version 1 or Version 2 configuration) Configures the WCCP web-cache service (service 0) on the Content Engine (transparent forward proxy server). This service permits the Content Engine to accept transparently redirected HTTP requests on a single port (port 80). If the requested content is not it its local cache, the Content Engine retrieves it from the origin web server, stores a local copy for future requests, and sends the client the requested content. Subsequent requests for the same web content is served from the local cache on the Content Engine. Only a single WCCP router is supported with WCCP Version 1; whereas, multiple routers (router list) are supported with WCCP Version 2. To enable the Content Engine to listen for WCCP intercepted HTTP traffic on ports other than the default port, configure the custom-web-cache service or a user-defined WCCP service (services 90 to 97).
WMT- Streaming	(For WCCP Version 2 configuration only) Configures the WCCP WMT media caching service on the Content Engine (transparent forward proxy server). If the requested content is not it its local cache, the Content Engine retrieves it from the origin streaming server, stores a local copy for future requests, and sends the client the requested content. Subsequent requests for the same WMT streaming content is served from the local cache on the Content Engine.

Caching Tab and Subtabs

Table A-3 lists the ACNS software, Release 5.1 or later features that can be configured from the Caching tab and subtab of the Content Engine GUI.

.

Table A-3 Content Engine GUI Caching Subtabs 

Subtab Option	Description
Auth. Cache	Configures cache authentication on the Content Engine. For more information, see the "Configuring Authenticated HTTP Cache Settings" section.
Bypass	(For WCCP Version 2 configuration only) Configures bypass on the Content Engine. For more information, see the "Configuring Bypass Settings on Standalone Content Engines" section.
Cache on Abort	Configures cache-on-abort features on the Content Engine. Determines the policy for object caching that the Content Engine should use if the web client aborts the download process. If this option is enabled, the Content Engine uses a selective algorithm to determine whether to continue to cache an object if the web client has aborted the download. If disabled, the Content Engine will always continue to download an object to the cache even if a web client has aborted the download.
Content Preload	Configures content preloading on the Content Engine. For more information, see the "Configuring Content Preloading for Standalone Content Engines" section.
Customized Error Page	Create HTTP customized error pages. If you create these customized pages, then the Content Engine displays the appropriate customized error page instead of the default error message when proxy errors occur. For more information, see the "Creating HTTP Custom Error Pages for Standalone Content Engines" section.
FTP Freshness	View or configure FTP object freshness factors for the Content Engine. For more information, see the "About FTP Cache Freshness" section.
FTP Proxy	Configures FTP incoming and outgoing proxies for the Content Engine. Proxy mode enables the Content Engine to operate in environments where WCCP is not enabled, or where client browsers have previously been configured to use a legacy FTP proxy server. DNS must be configured in order to support incoming FTP proxy requests. For more information, see the "Configuring FTP-over-HTTP Caching on Standalone Content Engines" section.
HTTP Freshness	View or configure freshness factors HTTP objects that are currently cached on the Content Engine. For more information, see the "Configuring HTTP Cache Freshness Settings" section.
HTTP Proxy	Configures HTTP incoming and outgoing proxies for the Content Engine. Proxy mode enables the Content Engine to operate in environments where Cisco's WCCP is not enabled, or where client browsers have previously been configured to use a legacy proxy server. DNS must be configured in order to support incoming HTTP proxy requests. For more information, see the "Configuring Nontransparent HTTP Forward Proxy Caching on Standalone Content Engines" section.
HTTPS Proxy	Configures HTTPS incoming and outgoing proxies. HTTPS proxy mode enables the Content Engine to service HTTPS requests sent by web clients that are configured to use an HTTPS proxy server. DNS must be configured in order to support incoming HTTPS proxy requests. For more information, see the "Configuring HTTPS Proxy Caching for Standalone Content Engines" section.
ICP Client	Configures a Content Engine cluster to generate ICP queries before retrieving the requested objects from the Internet. For example, specify how long the Content Engine should wait before retrieving the needed data directly from the Internet. By default, the Content Engine waits for 2 seconds; however, you can change this default. The range is 1 to 30 seconds. For more information, see the "Configuring Standalone Content Engines as ICP Clients" section.
ICP Server	Configures a Content Engine to act as an ICP server. Specify whether the Content Engine is the parent server or sibling server for the designated ICP client. If the Content Engine is the parent ICP server and cannot satisfy the ICP client's request, it forwards the request to another server on the Internet. If the Content Engine is a sibling ICP server and cannot satisfy the ICP client's request, it will send a failed response back to the ICP client. For more information, see the "Configuring Standalone Content Engines as ICP Servers" section.
LDAP	Configures the Content Engine to use an LDAP server for authentication purposes. To enable the Content Engine to use a specific LDAP server, enter the IP address of the LDAP server, and the port number that the LDAP server will be listening on. The default LDAP port number is 389. LDAP authentication is not performed if no LDAP servers are configured. For more information, see the "Configuring LDAP Authentication of HTTP Requests" section.
NTLM	Configures the Content Engine to use an NTLM server for authentication purposes. To enable the Content Engine to use a specific NTLM server, enter the host information. For example, specify the domain name (the domain name in which the user should be authenticated) and the domain server (the IP address or host name of the NTLM server). NTLM authentication will not be performed if no NTLM servers are configured. For more information, see the "Configuring NTLM Authentication of HTTP Requests" section.
Persist. Connect.	Configures persistent connections on the Content Engine. Persistent connections can be set for client-only, server-only, and all connections on the Content Engine. If the Strip NTLM Authentication headers option is turned off in the Content Engine, the NTLM authentication headers will be sent to the client. The Content Engine will not support NTLM authentication if persistent connections for all is turned off. For more information, see the "Configuring Persistent Connections" section.
Proxy Protocols	Configures proxy protocols for the Content Engine. The default behavior is that the Content Engine will retrieve the objects from the origin web server itself, or, if configured to use an outgoing proxy for this protocol, will forward the request to the specified outgoing proxy.
RADIUS	Configures the Content Engine to use a remote RADIUS server for authentication purposes. Configure the network parameters required to access the remote RADIUS database.
RealProxy	Enables the RealProxy GUI Administration page. Note that Real Proxy must be configured properly using the in order to start the Real Proxy. For more information about RealProxy, see the "Configuring RealProxy with the RealSystem Administrator GUI" section.
Transaction Logs	Enable and configure transaction logging. By default, transaction logging is disabled. For more information, see the "Monitoring Transactions with Standalone Content Engines" section.
URL Filtering	Configures URL filtering. For more information, see "Configuring URL Filtering on Standalone Content Engines."
WMT-Streaming	Enables WMT and configures WMT streaming parameters. For more information, see the "Configuring WMT Streaming and Caching Services for Standalone Content Engines" section.
