Technical Terms - Internet (A-Z) - Keep-Alive

What is the purpose of the Keep-Alive HTTP header?

• To allow a web server to use multiple connections for a single request

• To improve website performance by using a single connection for multiple requests

• To restrict access to certain web pages

• To encrypt data transmitted between the server and clients

Why is the Keep-Alive header not used in HTTP/2?

• Because it slows down the website performance

• Because HTTP/2 does not support persistent connections by default

• Because it is not compatible with modern browsers

• Because it requires more system resources from the web server

What happens when Keep-Alive is enabled on a web server?

• It creates persistent connections between the server and clients

• It reduces the page load time by closing connections quickly

• It increases the number of TCP connections for each request

• It blocks access to the website for certain users

What is the disadvantage of Keep-Alive in terms of system resources?

• It limits the number of requests allowed within a single connection

• It may overload the web server with persistent connections

• It slows down the website performance

• It requires more memory from the client's device

Which directive in Apache specifies the maximum time a persistent connection can stay open while waiting for new requests?

• RequestTimeout

• ConnectionTimeout

• KeepAliveTimeout

• MaxKeepAliveRequests

What is the purpose of the MaxKeepAliveRequests directive in Apache?

• To set the maximum number of requests allowed within a single connection

• To prevent servers from reaching maximum capacity

• To enable keep-alive on the server

• To specify the maximum time a connection can stay open

How can keep-alive be enabled on an Apache server?

• By using HTTP/2 protocol instead of HTTP/1

• By disabling the mod_headers module

• By adding a specific code to the server-wide include file or .HTACCESS file

• By setting the ConnectionTimeout directive to a high value

What is the purpose of the code snippet provided for enabling keep-alive on an Apache server?

• To disable keep-alive feature

• To set a timeout for each connection

• To specify the maximum number of requests allowed within a single connection

• To set the Connection header to keep-alive

What may happen if a web server has several thousand persistent connections open at once?

• The website performance may improve significantly

• The server may become unresponsive and unable to handle new connections

• The server may automatically close all connections

• The server may block access to certain users

What is the main benefit of using Keep-Alive for downloading webpage assets?

• It encrypts the assets for secure transmission

• It allows browsers to download all assets over a single connection

• It reduces the number of assets that need to be downloaded

• It increases the page load time by opening multiple connections
