One of the readers asked me about how to enable GZIP compression on the blogger platform & how to increase blogger loading speed if too many scripts are added to the HTML? First of all, let me tell you, Google's Blogger product comes with In-Built gZip feature. So you don't have to implement anything to make use of it. But you should know what it is.
Wait, I'll explain to you how it works. Say suppose you request a file from the webserver and suppose it's of a 200KB size HTML file, your browser talks to the web server and asked for it. Web-server replies with a 200KB file and sends it back as a response to your request. When it comes back to you, your browser downloads the 200KB file and displays the result on your screen. Now, what gZip actually does in the above situation is, it compresses a file from 200KB to say 40KB at the server-side itself. And that compressed file is sent back to you like a response, your browser will then downloads compressed file i.e. 40KB instead of 200KB, unzip it and displays the same result on your screen.
You must note that managing your blog running at top speed is essential. I'll explain what Gzip compression is and why it matters to speed up the loading of your website.
