This protocol is meant to act as a safe way to deploy and execute "One Click" controlled code in a restricted mode from the web while browsing.
Normally executable code is unmanaged (XP) / or has only lightly restricted access (Vista, 7) that may damage your operating system installation. By running managed code via the VWA Protocol you are ensuring the program is safe to run and will not damage your hardware or your Operating System installation.
VWA's (Visual Web Applications) are deployed via the zip compressed folder format. In order to have your code execute properly you must have the executable in the root folder of the zip and it must have the same name as the zip file.
