Nah, it’s not HTTP, those flags are specific to FTP.

I think it’s FTP too, but HTTP is also on port 80.

I feel like I should know this, but I can't remember if SSH uses port 21 or if that's just for FTP.

I'm a bit confused about the flags. I know 'P' indicates push, but does that help identify the protocol here?

I remember practicing a similar question where port numbers were key. If I recall correctly, port 21 is definitely for FTP.

I think the presence of port 21 suggests that it might be FTP, but I'm not entirely sure.

This seems like a straightforward question about the best way to approach custom app development with ease of updates in mind. I'll need to carefully consider the pros and cons of each option.
