The address, taken apart

Before following the parcel out the door, it is worth reading the whole address once, slowly.

One line, three statements. How to speak. Whom to contact. What to ask for. The whole plan for the journey fits in a line short enough to read aloud, and every piece of it has a name.

The whole line

The line itself is a URLConcept · lights on your mapURLUniform Resource Locator: a structured address telling a client where to go and how to communicate. It reads in parts. The scheme says how to speak, the domain says whom to contact, the path says what to request, and an optional query string carries extra details.. Case has seen thousands and read none of them, which is normal, and for the next thirty seconds we are going to be the kind of person who reads one.

How to speak

The front of the line names a protocolConcept · lights on your mapprotocolA shared set of rules for how systems talk: how messages start and end, how the content is arranged, what counts as an answer, what to say when something fails. Protocols are why two machines built by strangers who never met can hold a conversation.. Machines built by strangers can only converse if the rules were agreed in advance, and the rules for this conversation are HTTPConcept · lights on your mapHTTPHypertext Transfer Protocol: the main protocol of the web, defining how a client asks and how a server answers. The conversational grammar underneath nearly everything in this story., the web’s own grammar of asking and answering.

Except the line does not quite say HTTP. It says HTTPSConcept · lights on your mapHTTPSHTTP with encryption wrapped around it. The same conversation, sealed, so that machines passing the parcel along the way can read the address on the outside and nothing inside it.. Same conversation, sealed envelope. Every machine that passes the parcel along can read the address on the outside. None of them can read what Case put inside, and there is a date of birth inside.

The seal is also why a small padlock sits in the corner of Molly’s browser. What that padlock does and does not promise is a question this act will answer properly at the moment it matters most, which is the moment a card number is about to make this same trip.

Whom, and what

The middle is traversal.com, the domain from a scene ago, already turned into a number the network can use. And the end, /register, is the ask. Not the homepage. Not the route map Molly is reading. One specific thing: register me.

How to speak, whom to contact, what to ask for. The parcel knows everything it needs now, and the next scene opens the envelope.
