[Idpy-discuss] Questions about pyFF metadata downloads

Hello folks,

The UK federation team have discovered that a pyFF deployment is making a large number of metadata aggregate downloads from our Metadata Publication Service. In August, 34.74.200.81 made over 3,000 gzipped downloads of our metadata, downloading 36GB of metadata. As we update metdadata once per day, this deployment is clearly downloading excessively.

The IP address 34.74.200.81 is somewhere in Google cloud (81.200.74.34.bc.googleusercontent.com.) and the user agent string is pyFF/1.0.1. Is this anyone's deployment?

We also recommend that metadata downloaders make use of the conditional GET. Is it possible to configure pyFF to do conditional GET for metadata downloads?

Thanks,
Alex
