Browser Version Detection (OHS Customization Part 2)

One of my customers running EPM 11.1.2.1 faced issues last week when some of their end users had received new laptops with Internet Explorer 9 installed. It took some time for the IT department and EPM admins to figure out that the random problems that were being reported were actually caused by the unsupported browser version instead of other technical issues. We discussed how to work around the problem of unwanted browser versions - the most important method being centralized control over browser installations of course - but this gave me an idea of giving EPM end users a warning in case they were using an unsupported web browser.
