For both HNS-DFS and FNS-DFS we would want to check that the string isnt added right

Any reason for just facing FNS as value for FNS Blob user agent? FNS user agent can be there for FNS DFS as well, right?

We are adding the string only for FNS-Blob cases (since we wanted to check their usage only)
Initially we added "FNS-Blob" as string but then decided to shorten it to "FNS" since the endpoint we can check from the URL itself

Why this assume for connection type?
