IE8 Compatibility Mode User Agent?

When in Compatibility Mode, IE8 will display the string
MSIE 7.0

in the User Agent string. Is there any way I can determine that the browser used is
actually IE8, but in compatibility Mode???

No, that would defeat the point of Compatibility Mode.

I figured it out. If the user agent contains the string "MSIE 7.0" AND also the string
"Trident", it's IE8 in IE7 compatibility mode.

Actually, "Trident/4".

It is also possible for the user agent to contain "MSIE 6.0" and
"Trident/4", although this seems to be rarer.
