As a result, we can be confident that in most cases, the download request from the Proxy to this Web server will be satisfied quickly. We also see very consistent results using this service.

As part of the site, one can download files of various sizes. As with many sites hosting files, the URLs change regularly so that we cannot use the same link all the time. The following steps outline what is needed to verify whether a file is downloadable or not.
