I was going through OOB scenario as mentioned here (Windows scenario).

I have very few queries that I couldn’t get answer over internet.

• Does select into outfile or load_file allows writing directly to a remote filesystem on ubuntu and Windows?
• if by default, it does not allow writing to remote system, I assume we get this in Windows through \, UNC path. Is there any way for Ubuntu?
• What would be the case for Windows and Ubuntu regarding DNS and HTTP?

I think the core answer lies in the fact if the original functions allow network request.
