Looking at the _resolve_base_url() method of the StorageHelper class I can see that it is using furl to handle the path splitting for getting at the Azure storage account and container names.

Replicating the commands, the first one to get the Storage Account seems to have worked ok:

f = furl.furl(uri) account_name = f.host.partition(".")[0]Replicating above manually seems to give the same answer for both and it looks correct to me:

` >>> import furl

f_a = furl.furl(uri_a)
f_a.host.partition('.')[0]
'clearmllibrary'
f_b = furl.furl(uri_b)
f_b.host.partition('.')[0]
'clearmllibrary' `
