Are you sure that it isn't evaluated?  I can imagine that the script
registers an event listener for the onload event of the Window object or
such.  In this case the listener may be registered, but never triggered.

There may be other reasons why the code doesn't work as expected, even
though the script is evaluated.

No.  (That would be necessary, though, if you would evaluate code in a
string literal.)

I don't think it makes sense to set a Content-Type request header, when
the body of the request is empty.
