Hi TSM,

to identify Internet Explorer regardless of its version, you have to check for the pattern "MSIE " or "Trident/".

switch -glob -- [HTTP::header value "User-Agent"] { 
    "Mozilla/*MSIE *" - "Mozilla/*Trident/*" {
        set is_internet_explorer true
    }
    default {
        set is_internet_explorer false
    }
}

Note: For further information which UA-String is used by which browser you may check up the following page [click me].

Cheers, Kai
