How data gets where it's going
The first line above, HTTP/1.1 200 OK, means that the requested web page is available. Other codes may also be returned. For example, the code 404 means the server cannot find the requested page.
When found, the web page is sent via TCP as a series of data packets, each with a header that specifies its destination and its order in the data stream. The various packets can take different paths to reach their destination.
