My google app engine website is getting errors on the main url for HEAD requests because I am not accepting them. According to this, the HEAD request is for "testing hypertext links for validity, accessibility, and recent modification"
What should be my "normal" response to HEAD requests be?
I started accepting HEAD requests, to stop the errors from showing in my logs, but only on the main url.
Can someone point me in the right direction?
Implement you head method(s) just like the get one(s), just skipping the writing of the body. You should do that for every URL that can be linked to, exactly because a well-behaved checker that's validating the links should use HEAD when it doesn't need the body.
Simplest is often to factor out the get functionality to a separate auxiliary method _foo that takes a boolean needbody argument -- get calls self._foo(True), head calls self._foo(False). _foo, if it sees its needbody argument is false, can bail out as soon as it has generated all headers (and must make sure it doesn't generate a body).
