Why do you think this is missing ? fpWeb does not really care about the method.

What is DRY (other than opposed to WET ?)

All you need to do is

   If Compare(ARequest.Method,'UPDATE') then
     DoYourUpdate(ARequest);

If you really want different events for the HTTP methods, you can make a
descendent of TCustomHTTPModule which overrides HandleRequest() and which then
examines the HTTP method and calls the appropriate callback for the various HTTP 
methods.

It can't possibly take you more than 15 minutes to code this, plus an
additional 10 to register your new module in Lazarus.

And if you care to donate it, I'll put it in FPC.
