Hi MSZ,
It may be required by your application, but only the developer of the application knows for sure. For further reading on the purpose of the X-Wap-Profile header see...
https://en.wikipedia.org/wiki/UAProf
But the header should have at least a value to become RFC conform. You could now either allow non empty headers in ASM, or use an iRule to remove every empty instance of "X-Wap-Profile" before passing the request to ASM.
when HTTP_REQUEST {
if { [HTTP::header value "X-Wap-Profile"] eq "" } then {
HTTP::header remove "X-Wap-Profile"
}
}
Cheers, Kai
