I’m wondering if anyone has a good resource detailing exactly what happens when a browser makes a request to a rails app. I’m interested in everything: how the server handles the connection, how the route gets parsed, when does middleware come in, and so on. I would love to see something detailed all the way down to exactly what methods get called, and what objects get instantiated.

I feel like I don’t have a great handle on all the details, and this causes me to grope in the dark for the best solution to certain problems. Any suggestions for how to learn more about this are welcome.
