To complete a check-out operation, View Transfer Server still must transfer each user's linked-clone OS disk
and persistent disk from the datacenter over the WAN, but these disks are a fraction of the size of the base
image.
1 Configure View Connection Server to Support HTTP Caching of View Composer Base Images on
page 333
To allow a caching proxy server to pass on View Composer base images and other data between local
desktops and the datacenter, you must configure certain settings in View Connection Server.
2 Limit the Size of Base-Image Package Files to Allow Caching on page 334
A View Composer base-image package can contain files that are larger than a gigabyte, too large for
many
proxy servers to cache. You can configure View Transfer Server to split base-image packages into
files that are no larger than the capacity of the proxy-server cache.
3 Configure Client Computers to Transfer Data Through a Proxy Server on page 334
To support HTTP caching, you must configure the client computers that host local desktops to transfer
the desktop data through a caching proxy server. You also must configure the client computers to use
the proxy server's HTTP address for internet connections.
4 Configure a Proxy Server to Cache View Composer Base Images on page 335
When you set up a proxy server to support HTTP caching for local desktops, you must configure the
capacity of the cache and the HTTP connection method.
Configure View Connection Server to Support HTTP Caching of View Composer
Base Images
To allow a caching proxy server to pass on View Composer base images and other data between local desktops
and the datacenter, you must configure certain settings in View Connection Server.
You use two separate View settings to configure SSL encryption for the following two types of data:
n
View Composer base images
n
Other linked-clone desktop data, including OS disks and persistent disks
You must disable SSL encryption of transfers of base-image package files from the Transfer Server repository
to local computers. Disabling SSL allows the proxy server to access and cache the package-file contents.
Disabling SSL does not expose the base-image data. The data is encrypted when you publish the base image
to the Transfer Server repository and remains encrypted when it is downloaded to the proxy server over the
WAN.
You can choose whether to use SSL encryption of transfers of all other local-desktop data. To permit other
local-desktop data to pass through the caching proxy server, you must configure the proxy server to allow the
use of the HTTP CONNECT method or you must enable SSL encryption of local-mode operations on View
Connection Server.
If you use SSL encryption, you do not have to change proxy server settings, but SSL encryption can affect the
performance of transfers of linked-clone OS disks and persistent disks.
You must configure these SSL settings on each View Connection Server instance that delivers View services
to the clients for which you configure HTTP caching.
Procedure
1 In View Administrator, click View Configuration > Servers.
2 Click the View Connection Servers tab, select a View Connection Server instance, and click Edit.
3 Click the Local Mode tab and deselect Use SSL when provisioning desktops in local mode.
This setting disables SSL for downloading base-image package files from the Transfer Server repository
to local computers.
