The HTTP Keep-Alive, or also commonly referred to as an HTTP persistent connection, is an HTTP header that allows a connection between the server and client (browser) to remain open to transfer multiple files.<\/p>\n

[\/vc_column_text][vc_custom_heading text=”Benefits of the HTTP Keep Alive Header” font_container=”tag:h3|font_size:30|text_align:center|color:%232b2b2b|line_height:1.5″ use_theme_fonts=”yes”][vc_column_text]<\/p>\n

Without the HTTP Keep Alive header, there would have to be a connection opened for each file that needs to be accessed and transferred. If the Keep Alive function is turned off, a user would have to initiate a separate request each time a filed is needed. By turning this on, it allows the server to serve the necessary resources over a single connection, which helps to reduce CPU\/memory usage on the server. Additionally, developers can set the number of requests allowed (MaxKeepAliveRequests) and timeout (KeepAliveTimeout) for this header that best meet your website\u2019s requirements.<\/p>\n
