I am getting errors every few seconds being reported on my dashboard. However my pages load OK without error. When I delve from the error which is reported at /_ I get the following type of log entry. What can this mean?

405 is "Method Not Allowed"

That request is using a HEAD method. Your application must not be able
to handle them. Its likely only setup to handle GET's (which is what a
browser mostly uses) and maybe POST's if you have any forms.

So could modify the app so that it supports HEAD requests.

Some of the reasons why

Or can just ignore them. Nothing says you absoluely have to support
HEAD requests, although it is good practice to do so.

That IP address, seems to be from http://planetflow.planet-lab.org/ so
they are doing some sort of research.


You could also block them

to save you a bit of money.

The weird thing is, that this large number of errors

22119
in the dashboard summary is not at all reflected in the number of requests. And if I go to logs and do a search on errors I only get 20 errors!

Why is the dashboard number so huge. Even the total number of requests is only round 200! (last 24 hours).
