WCCP Tab and Subtabs

Table A-1 lists the ACNS 5.1 software features that can be configured from the WCCP tab and subtabs of the Content Engine GUI.

.

Table A-1 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 Content Engine to cache custom web traffic.
Reverse Proxy	(For WCCP Version 2 configuration only) Configures the reverse proxy service on the Content Engine. When the Content Engine is configured to support this WCCP service, it acts as a reverse proxy; the Content Engine acts as a proxy on behalf of the origin web server. This WCCP service is only available when WCCP Version 2 is enabled.
RTSP	(For WCCP Version 2 configuration only) Configures the Content Engine to cache RTSP traffic.
Services	(For WCCP Version 2 configuration only) To configure the Content Engine to cache web traffic using multiple ports, use WCCP Version 2 services 90 to 97. To configure these generic WCCP Version 2 services, use this WCCP Services page.
Web Cache	(For WCCP Version 2 configuration only) Configures the Content Engine to cache standard web traffic.
WMT-Streaming	(For WCCP Version 2 configuration only) Configures WMT streaming caching service on the Content Engine. When the Content Engine is configured to support this WCCP service, the Content Engine is configured to cache WMT streaming traffic.

Caching Tab and Subtabs

Table A-2 lists the ACNS 5.1 software features that can be configured from the Caching tab and subtab of the Content Engine GUI.

.

Table A-2 Content Engine GUI Caching Subtabs 

Subtab Option	Description
Auth. Cache	Configures cache authentication on the Content Engine. For more information about this topic, see the "Configuring Authenticated HTTP Cache Settings" section.
Bypass	(For WCCP Version 2 configuration only) Configures bypass on the Content Engine. •Load bypass—If a Content Engine becomes overwhelmed with traffic, it can use the load bypass feature to re-route overload traffic back out to the Internet. The Content Engine can only bypass WCCP-redirected traffic, it can bypass proxy-style requests. •Authentication bypass.—Some websites, due to IP authentication, may not allow the Content Engine to connect directly on behalf of the web client. In order to avoid a disruption of service, the Content Engine can use the authentication bypass feature to generate a dynamic access list for these client-server pairs. Authentication bypass triggers are also propagated upstream and downstream in the case of hierarchical caching. For more information about this topic, see the "Configuring Bypass Settings" 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. For more information about this topic, see the "Configuring HTTP Cache On Abort" section.
Content Preload	Configures content preloading on the Content Engine. For more information about this topic, see the "Configuring Content Preloading" section.
FTP Freshness	View or configure FTP object freshness factors for the Content Engine. For more information about this topic, see the "Setting FTP Cache Freshness" section.
FTP Proxy	Configures FTP incoming and outgoing proxies. 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 about this topic, see the "Configuring FTP Connection Settings" section.
HTTP Freshness	View or configure freshness factors for HTTP objects requested. For more information about this topic, see the "Configuring HTTP Cache Freshness Settings" section.
HTTP Proxy	Configures HTTP incoming and outgoing proxies. 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 about this topic, see the "Configuring HTTP Connection Settings" 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 about this topic, see the "Configuring HTTPS Proxy Settings Using the Content Engine GUI" 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 about this topic, see the "Configuring ICP Client Settings" 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 about this topic, see the "Configuring ICP Server Settings" 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 about this topic, 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 about this topic, see the "Configuring NTLM Authentication for 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 about this topic, 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 its 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 ACLI in order to start the Real Proxy. For more information about RealProxy, see the "Understanding the RealProxy Streaming Media Solution" section.
Transaction Logs	Enable and configure transaction logging. By default, transaction logging is disabled. For more information about transaction logs, see the "Transaction Logging" section.
URL Filtering	Configures URL filtering. For more information on URL filtering, see "Configuring URL Filtering."
WMT-Streaming	Enables WMT and configures WMT streaming parameters. For more information about this topic, see the "Enabling WMT on a Locally Deployed Content Engine" section.
