We want to enable InstantCommons on cloud but are not sure how much traffic this will result in for real commons. We want to make sure we're being good internet citizens.

Questions we want answered:

• Does it cache:
  • • The actual image files on the server?
      • Check this by turning on InstantCommons locally + adding loads of files + using the browser network tools to see if they come directly from commons or if they come from the local wiki.
    • Metadata i.e. the links to those files?
  • check this by looking in the cache and seeing whether stuff is cached.

If so:

• where are the cashed files stored?
• will we get rate limited?
  • this is hard to be certain about but maybe try adding loads (50+) of files and see what happens locally
