[mod_python] Why do I get a 405 ERROR on HEAD REQUEST?

I don't use the publisher, but i take a look and find something interesting

As you find if that's not a "GET" or a "POST" an http error is returned to
the client :

publisher.py :

47    req.allow_methods(["GET", "POST"])
48    if req.method not in ["GET", "POST"]:
49        raise apache.SERVER_RETURN, apache.HTTP_METHOD_NOT_ALLOWED

But somewhere the method "HEAD" is correctly handled :

155        if req.method != "HEAD":
156            req.write(result)
157        else:
158            req.write("")
159        return apache.OK

Since the result is everything that's should be send after the header, this
It's look like the previous code [47-49] was added after but, i don't know

Somebody have an idea ?

Well, you should either write your own handler, or keep the modified
publisher if it fit your needs.

it seems that adding "HEAD" to this code in modpython/publisher.py fixes
the issue:

(around line 41)

def handler(req):
    req.allow_methods(["GET", "POST"])
    if req.method not in ["GET", "POST"]:

is there a more elegant way to fix this?  why does the publisher handler
set the allowable methods?  shouldn't i have control over that?   do i
and just not know it?  or do i just have to create my  own publisher?
