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 In the View Servers panel, select a View Connection Server instance and click Edit.
3 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.
4 If you do not set the caching proxy server to use the HTTP CONNECT method, select Use SSL for Local
Mode operations.
This setting affects transfers of all other local-desktop data.
Limit the Size of Base-Image Package Files to Allow Caching
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.
When you publish a package in the Transfer Server repository, View Transfer Server creates package files of
the specified size. You must configure the size limit before you begin publishing packages to the repository.
View Transfer Server does not split existing package files to conform to the size limit.
You can set this value on any View Connection Server instance in a replicated group. When you change View
LDAP, the change is propagated to all the replicated View Connection Server instances.
Prerequisites
Familiarize yourself with using the vdmadmin command with the -T option. See “Setting the Split Limit for
Publishing View Transfer Server Packages Using the -T Option,” on page 310.
