B4J Question Ignore mreq / mresp globals in server handler class

[avalle]

I see in the server guide and in most server examples that

Private mreq As ServletRequest        'ignore

comes with this "ignore" comment.
What does ignore mean here?

The Handle Sub typically contains the following:

Sub Handle(req As ServletRequest, resp As ServletResponse)
    mreq = req
    mresp = resp

Is there any difference in referring to mreq vs. req or mresp vs. resp?

If I need to call a Sub within the same Handler class, which needs to work on the response, is it ok to use the mresp global within the Sub, or instead should I ignore mresp and pass resp as a parameter of the Sub?

Sub Handle(req As ServletRequest, resp As ServletResponse)
    mreq = req
    mresp = resp
    MyPrivateSub
End Sub

Sub MyPrivateSub ()
    mresp.write("Hello!")
End Sub

Sub Handle(req As ServletRequest, resp As ServletResponse)
    mreq = req
    mresp = resp
    MyPrivateSub(resp)
End Sub

Sub MyPrivateSub (response As ServletResponse)
    response.write("Hello!")
End Sub

Which one is correct: Option 1 or 2?
And if Option 1 is fine, why ignore it?

'ignore tells the compiler to ignore warnings on that line. In many cases these global variables are unused so the compiler will show a warning about unused variables.

Please ignore the 'ignore.

Thanks Erel, I didn't know the purpose of the 'ignore comment is to suppress the compiler warning for unused variables.
So option 1 is ok, great!
