How Can I Do Browser Document Redirect?

I noticed older internet browsers do not process the css & jscript very well in the newer releases. I want to display a popup or redirect to page that tells the customer their browser is incompatible with the site

Any suggestions on using the right working code to work based on browser document type? maybe someone already have snipplets ?


I have made a quick search in Google and found many examples. If you face any issue with their implementation, please contact us.
