When talking to CouchDB you need to make requests. Making a request includes opening a network connection to CouchDB, exchanging bytes, and closing the connection. This is done every time you make a request. Other protocols allow you to open a connection, exchange bytes, keep the connection open, exchange more bytes later—maybe depending on the bytes you exchanged at the beginning— and eventually close the connection. Holding a connection open for later use requires the server to do extra work.
If you send Accept: application/json in your request, CouchDB knows that you can deal with a pure JSON response with the proper ContentType header and will use it instead of text/plain. < Content-Length: 12 The Content-Length header simply tells us how many bytes the response body has. < Cache-Control: must-revalidate This Cache-Control header tells you, or any proxy server between CouchDB and you, not to cache this response. < This empty line tells us we’re done with the response headers and what follows now is the response body.
