     4 // This server-side script is used for browser_thumbnails_update.  One of the

     5 // main things it must do in all cases is ensure a Cache-Control: no-store

     6 // header, so the foreground capture doesn't interfere with the testing.

     8 // If the querystring is "simple", then all it does it return some content -

     9 // it doesn't really matter what that content is.

    11 // Otherwise, its main role is that it must return different *content* for the

    12 // second request than it did for the first.

    13 // Also, it should be able to return an error response when requested for the

    14 // second response.

    15 // So the basic tests will be to grab the thumbnail, then request it to be

    16 // grabbed again:

    17 // * If the second request succeeded, the new thumbnail should exist.

    18 // * If the second request is an error, the new thumbnail should be ignored.
