Yes, you can check the content-type at the time of the echo and whatever
the value is is what will go out. Unless of course output buffering is
turned on, in which case the echo doesn't actually output anything until
the buffer is flushed, and that would be the point at which you would
need to check it. The buffer can also be tossed, so the buffered echo
may not ever go out.
