I hate it when you get tunnel vision and forget simple solutions exist. Especially when you make yourself sound dumb in doing so.

Spent a bunch of time trying to wrap my head around how you could send data from one website to another and dynamically load content and all this other stuff, only to be told a GET call would make it a lot easier.

With my head in the clouds thinking of complex solutions I said "can you open a new page with a GET call?"

Can you. Open. A new page. With a GET call.

Yes, dumbass, of course you can. Here I am trying to figure out how it's possible to intercept data from a different websites HTTP call to the server and I asked if it's possible to do what ~literally~ a link does.
