Configure a cache redirection virtual server
By default, a cache redirection virtual server forwards cacheable requests to the load balancing virtual server for the cache, and forwards non-cacheable requests to the origin server (except in a reverse proxy configuration, in which non-cacheable requests are sent to a load balancing virtual server). There are three types of cache redirection virtual servers: transparent, forward proxy, and reverse proxy.
A transparent cache redirection virtual server uses an IP address of * and a port number, usually 80, that can accept HTTP traffic sent to any IP address that the appliance represents. As a result, you can configure only one transparent cache redirection virtual server. Any additional cache redirection virtual servers that you configure must be forward proxy or reverse proxy redirection servers.
Add a cache redirection virtual server in transparent mode by using the CLI
At the command prompt, type the following commands to add a cache redirection virtual server and verify the configuration:
- add cr vserver <name> <serviceType> [<IPAddress> <port> ] [-cacheType <cacheType>] [-redirect <redirect>]
- show cr vserver [<name>]
Example:
add cr vserver Vserver-CRD-1 HTTP * 80 -cacheType TRANSPARENT -redirect POLICY
> show cr vserver Vserver-CRD-1
Vserver-CRD-1 (*:80) - HTTP Type: CONTENT
State: UP ARP:DISABLED
Client Idle Timeout: 180 sec
Down state flush: ENABLED
Disable Primary Vserver On Down : DISABLED
Default: Content Precedence: RULE Cache: TRANSPARENT
On Policy Match: ORIGIN L2Conn: OFF OriginUSIP: OFF
Redirect: POLICY Reuse: ON Via: ON ARP: OFF
Done
Modify or remove a cache redirection virtual server by using the CLI
- To modify a virtual server, use the
set cr vservercommand, which is like using theadd cr vservercommand, except that you enter the name of an existing virtual server. - To remove a virtual server, use the
rm cr vservercommand, which accepts only the <name> argument.
Add a cache redirection virtual server in transparent mode by using the GUI
-
Navigate to Traffic Management > Cache Redirection > Virtual Servers.
-
In the details pane, click A**dd.
-
In Create Virtual Server (Cache Redirection), specify the required parameter values.
-
In Protocol, select a supported protocol (for example, HTTP). If the virtual server is to receive traffic on a port other than the standard port for the selected protocol, enter a new value in the Port field.
-
Click the Advanced tab.
-
Verify that Cache Type is set to TRANSPARENT and Redirect is set to POLICY.
-
Click Create, and then click Close. The Cache Redirection Virtual Servers pane displays the new virtual server.
-
Select the new cache redirection virtual server to display the details of its configuration.
