Manage video caching sources

You can manage your video sources either globally, by configuring global settings, or individually, by changing status of a video source.

Configure global settings

Global settings enable you to configure the feature at the appliance level. Irrespective of the video sources you have added, these settings are applicable to the entire video caching feature on the appliance. You can:

Configure the maximum size of the cached objects
Configure a DNS suffix
Configure Caching Ports
Update the video caching policy file

You can configure a maximum size for cached objects. An object larger than this limit is not cached. By default, the maximum caching object size is 100 MB.

For the URLs that do not contain complete domain names and require domain name suffixes to be added to the hostname of the video server, appending a default domain name is necessary for eliciting a response from the server. For example, when you access the http://training/CitrixSD-WANWANOP\_VideoCaching.mp4 video, the appliance might be expected to translate the URL to http://training.example.com/CitrixSD-WANWANOP\_VideoCaching.mp4. In this case, you must specify example.com as the domain name suffix.

The video caching feature requires a port number for the HTTP video server. The default is port 80. If your HTTP video server uses a port other than this well-known HTTP port, you must add the port number to the list of caching ports.

To configure global settings for video caching:

Navigate to Configuration > Video Caching > Set Global Parameters.
In the MaxCaching Object Size field, set the maximum size for cached objects.

Select a value from the available limits. An object larger than this limit is not cached.
In the DNS Suffix field, enter a domain name to append to URLs that do not contain complete domain names and require domain name suffixes to be added to the host name of the video server.
In the Caching Ports field, type the HTTP video server’s port to add it to the list of caching ports. Optionally, add multiple port numbers separated by commas.
Click OK.

The appliance uses 10% of the allocated disk space for management purposes. When the disk usage reaches 90% of the allocated disk space, that is an indication of the disk being full. To cache more video objects, the appliance removes the least used objects from the video cache. You need not clear the cache unless the cache serves stale video objects.

To clear video cache, navigate to Configuration > Video Caching and click Clear Video Cache.
