It's not clear what kind of protocol is

[vemv]

Hi,

while I have a basic understanding of CDP, and have successfully used it, CDP's documentation does not do a great job at describing what do they mean exactly by 'protocol'.

• Is CDP a specific, distinct protocol, like SMTP, FTP, POP, etc?
• Is CDP 'just HTTP'? A subset thereof?
• Is CDP 'just websockets'? subset thereof?
• Something else?

The way I see it, a set of type definitions like browser_protocol.json do not constitute a protocol.

Those type definitions may be part of it, but what I believe to be missing is how communication happens.

Thanks much,

-V

@vemv CDP sits on top of JSON-RPC, though spec-wise it appears to align closest with the 1.1 Object Spec.

The transport for CDP is almost entirely over websockets, though using a pipe is supported.
