¿Es decir, 6 omitidos en los modos de compatibilidad de Equiv HTTP?

Question

Este artículo especifica, es decir,9 (Edge), IE8, IE7 e IE5 como modos de documento HTTP-EQUIV válidos.¿Por qué IE6 se omitió?¿Hace lo mismo que IE5?Mi compañía admite IE6 +, por lo que quiero encontrar una forma confiable de probar los cambios de UI de compatibilidad de IE6 sin requerir una VM.

Answer 1

The article specifies the compatibility modes IE (8-9) can run in. IE5(.5) equals to quirks mode. IE8 cannot run in IE6 compatibility mode. IE6 does not absolutely render the same as IE5(.5) (unless it's in quirks mode).

If you want a reliable way to test in IE6, IE7, etc., you should try something like IETester (which I found to be reliable), Spoon, etc. if you don't want to use VMs.

You should also check this SO question. As stated there:

Also, don't trust IE8 compatibility mode.
