Beroende på vad användarna har för skärmupplösning så vill jag att de dirigeras vidare till en speciell sida. De med 800x600 ska skickas till 800x600.html och de med 1024x768 till 1024x769.html osv. Hur gör jag.

Nu skall du få en ordentlig laddning javascript som jag fann på nätet för diverse saker som kan vara av intresse. Med din if-sats så kan du sen bara säga location.href='800.htm' osv..
