For Head method - As it only request for the header part of the response , there will be no body if we use Head http method . This method is generaly used for checking any change in header values like testing hypertext links for validity, accessibility, and recent modification.

Hi,

Can anybody tell me how to generate HEAD request from browser. I am trying it using method="head" is form element. But the in servlet which is defined in action element the request.getMethod() return GET in service method ( I have overriden the service method because for every Http Method except for POST it is executing doGet()).

Thanks

hi

overriding the get request automatically supports
http head requests.
a head request is a get request that returns no body
thats why request.getMethod() return GET
