GET and HEAD requests

Hi,
There are a few things which I am not too sure regarding how Servlet 2.3 handles GET and HEAD requests. Please help.
1. If doHead() method in HttpServlet is overridden, will it be called by the server when there is a HEAD request?
2. Is the HttpServletResponse parameter in the doHead() method a special type of response object which contains no content (only status line and headers)?
3. Since there is a doHead() method available, and if doGet() is overridden, will a OPTIONS request cause doOptions() to still return the header :
Allow : GET, HEAD, TRACE, OPTIONS
Note that HEAD is in the Allow header.
Thanks in advance.
