All the tool does right now is visit urls and get the request data. It could be HTML or JSON responses from API calls.
It has a profile flag to profile its own performance.
Apart from learning Rust, the "difficulty" of this tool, so to speak, is in attempting to use low level primitives to create and send my own HTTP GET requests over a TCP Stream.

I've named the tool visit, so it would be (profile flag is optional):
visit.exe --url <the-url> --profile <count>
