Error accessing iOS devices – VMware Horizon View 7.x and F5 BIG IP APM 12.x

If you have recently upgraded to Horizon 7.x and use BIG IP APM version 12.1 you may realize that your Apple iPad and iOS devices don’t work. The following error message on the Horizon View Client is noticed. (Screenshot from iPad)

Error: The Horizon server connection failed. Error the connection timed out.

Resolution:
In our scenario all the other devices such as Android, Windows etc. was working fine. To fix this problem we had to create a new F5 iRule(Name it F5-APM-iOS-fix):

when HTTP_REQUEST {

    if { [HTTP::header "Origin"] ne "" } {

        HTTP::header remove "Origin"

    }

}

Note: Make sure you apply this iRule on the existing Horizon View iApp or/else it will not allow you to apply the iRule, may get a error message.
