It seems to me that for each path element in a URI a mod_python handler
will be invoked. This applies to PythonAuthenHandler,
PythonHeaderParserHandler and so on.
Since I'm making a database request in my PythonAuthenHandler, this
quickly becomes a problem.
Example:
http://lucene.moonspawn.scanmine.com/ =>
AuthenHandler::authenhandler called: 1
index got called once
http://lucene.moonspawn.scanmine.com...dler.py/search =>
AuthenHandler::authenhandler called: 1
AuthenHandler::authenhandler called: 2
/search got called once
http://lucene.moonspawn.scanmine.com/search.html => (using mod_rewrite)
AuthenHandler::authenhandler called: 1
AuthenHandler::authenhandler called: 2
AuthenHandler::authenhandler called: 3
/search got called once
I get the same behavior on three separate installations
So, either I've got a miss-configuration which results in multiple calls
to handlers or.., this is expected behavior, and there is a technique to
avoid this or..., this is expected and, for reasons that escapes me,
desired behavior.
I'd greatly appreciate any help and suggestion

Well, the thing that's missing here is the code of your AuthenHandler
(or some detail about which standard component you think is being used).
Is it possible you are making internal redirects, for example?
The information about using mod_rewrite does imply you are spending time
on authentication rather more frequently than you strictly need to, but
it's difficult to figure out from just the information given.

Hi Steve,
The configuration and "files" shown below results in the "Example" of my
orignal post.
httpd.conf:

req.write("<html><head><title>Search /search Page</title><head><body>## '/search' got called once</body></html>")
"""
Now, I've "solved it" with a single PythonHandler (dropping
PythonAuthenHandler and publisher):
def handler(req):
if not req.headers_in.get("Authorization",0):
req.err_headers_out["WWW-Authenticate"] = 'Basic realm="Restricted\
area"'
raise apache.SERVER_RETURN, apache.HTTP_UNAUTHORIZED
meth,auth = req.headers_in.get("Authorization").split(" ")
user,pw = decodestring(auth).split(":")
args = dict([(a[0],a[1]) for a in util.parse_qsl(req.args or '')])
if dbmdbValidate(user,pw,req.server):
return myMethod(req,**args)
else:
return apache.HTTP_UNAUTHORIZED
This seems to do exactly what I want. Guess I should have tried a litle
harder before posting.
How ever, I'm still curious to why the PythonAuthenHandler is called for
each path element.
