Technical update on some new hotfixes that were rolled out to resolve some issues with HTML5 connectivity with VMware Horizon 7.1/7.2 with BIG-IP Access Policy Manager.
What is VMware Horizon HTML Access?
VMware Horizon HTML Access provides the ability for employees to access applications and desktops via web browsers (HTML5 compliant) and without the need for additional plugins or native client installations. This method of access provides advantages to customers who utilize very strict software installation requirements and require access to their internal resources, as well as customers who utilize BYOD based implementations. VMware Horizon HTML Access is an alternative way of accessing company internal resources without the requirement of software installation.
What does the Hotfix Do?
The Hotfix is designed to allow the newer version of the VMware Horizon HTML Access Clients which were upgraded with new URI information to be accessible via APM. Without this hotfix, customers who upgrade to the Horizon 7.1/7.2 code may experience an issue where HTML5 will not connect to the VDI Resource (blank or grey screen.)

Here is an example of a working configuration. Notice the f5vdifwd string in the URL:
Note that the fixes are incorporated into Hotfixes. F5 recommends to use the Hotfix builds over the iRules listed in the below article. If the iRules are in place when upgrading to a build with the incorporated fix, make sure that the iRule is removed.
