HTTP Header - What is Connection: close and keep-alive

[Gateman]

What is connection: close, one of the HTTP connection headers? What effect do these values have on SEO? What is another answer, connection: keep-alive? We will talk about the details in this article.

Connection: keep-alive

If the value sent is keep-alive, it means that the connection is persistent and the network connection will be open for subsequent requests to the same server. It helps to send and receive multiple http requests using a single TCP connection, as opposed to establishing a new connection for each request. This value is the default for HTTP/1.1 requests.

Connection: close

The response indicating that the client (server) wants to close the connection. This value is the default for HTTP/1.0 requests.
