Description

When registering templates with CloudStack, it is necessary to provide a URL from which the template can be downloaded.

CloudStack validates the format of these URLs, but it does so quite aggressively, sometimes rejecting URLs that are perfectly valid.

In particular, CloudStack expects and requires the URL to carry a file extension in the end that matches the expected template, eg. ".vhd" or ".vhd.gz". If the URL doesn't have such an extension in the end, it will be rejected, even if it is a perfectly valid URL from which a VHD can be downloaded.
