HEAD method

[Antoine Latter]

Hi Happstack,

Does anyone have any experience dealing with the HEAD HTTP method and
Happstack? Currently a handler guarded by, for example, 'methodSP
GET', will fail for a request of method HEAD.

This is understandable from a strictly technical level, but it seems
to be against the spirit of the RFC.

Maybe head requests aren't that useful, but I noticed this when
testing out a site with 'curl -I', which defaults to a method of HEAD
(as I told it to only display returned headers with the I switch).

I guess I'm more looking for anyone who has thought about this, rather
than requesting changes take place.

Hello,

If you want HEAD to work then you need to do:

  do methodM [GET, HEAD]

        ...

instead of just, methodM GET.

later when the response is send, it will check if the rqMethod was HEAD and not send the body. See line 219:

However, it appears that SendFile branch needs a guard as well..
