Reader function is unable to process the url

[sviaro]

Calling the plug-in reader function on url results in error message instead of a file download:

Thanks for reporting! We need to add a condition that handles urls, nice catch!
Maybe using urlparse, from which we could get a path and then the file extension if it is a single file. It it is a .zip, then it is probably a folder.
