We are running a vb.net webforms website. I need to implement a solution to either prevent or warn IE users with a version below 8. Im looking into possible solutions for this. Ive looked at modernizr, but that only looks at features, i want to simply block by IE version.
Also preferably i dont want to write my own user agent logic but use 'proven technology', as in a third party solution. Ideally it also takes into account wether or not IE is running in compatibility mode < IE8.
IM interested to hear what everyones take is on this and what the possible solutions are.
