Question

Assume that you have made a request for a web page through your web browser to a web server. Initially the browser cache is empty. Further, the browser is configured to send HTTP requests in non-persistent mode. The web page contains text and five very small images. The minimum number of TCP connections required to display the web page completely in your browser is_______.

Correct answer 6 to 6 Solution In non-persistent HTTP connections, a new TCP connection is established for each object requested. 1. First, a TCP connection is opened to fetch the base HTML file (text). After the transfer, the connection is closed. 2. The browser parses the HTML and finds references to 5 images. 3. For each of the 5 images, a separate TCP connection must be established to fetch it. Total TCP connections = 1 (for HTML) + 5 (for images) = 6. Turn this into a strength.
