What happens when a browser is used to send a request to a server?

The browser sends an HTTP request message to the server, asking it to send a copy of the website to the client (you go to the shop and order your goods). This message, and all other data sent between the client and the server, is sent across your internet connection using TCP/IP.

What will an HTTP server do in response to a browser GET request?

Once the TCP connection is established, the client sends a HTTP GET request to the server to retrieve the webpage it should display. After the server has sent the response, it closes the TCP connection. GET requests are one kind of HTTP method a client can call.

What does a server do in HTML?

Which is the component that processes the browser request and send the response back to the browser?

server
Your computer, or smartphone, or any other device you’re browsing with is called a client. The other half of the web equation is called a server because it serves you the data you request. Their communication is called a client-server model, whose main concern is receiving your request and delivering the response back.

How do servers respond to get requests?

As a quick summary, the HTTP/1.1 protocol works as follows: The client (usually a browser) opens a connection to the server and sends a request. The server processes the request, generates a response, and closes the connection if it finds a Connection: Close header.

HTTP server
On a web server, the HTTP server is responsible for processing and answering incoming requests. Upon receiving a request, an HTTP server first checks if the requested URL matches an existing file. If so, the web server sends the file content back to the browser. If not, an application server builds the necessary file.

How to send HTTP response from node?

Sending response from node will be made simpler with the use of express.js in upcoming articles. Headers are important in both http request and response. They are useful in identifying the right content type and accept type from server and client. Cache-control is one such header which determines caching mechanisms between server and client.

Can the server send a second response to the browser?

(I’ll skip over keep-alive and methods that allow the server to push content to the browser–those are all far beyond the simple learning purpose you seem to have in mind here.) Suffice it to say that it is inappropriate to send a second response to the browser when it hasn’t asked for it.
