Clear Cache

The cache memory may contain Images, Files and Documents that are being pulled from the site that you frequently visit.

Now, How Cache Works? Well, When you visit a website with Google Chrome for the first time, it might take a little longer than usual. Once you have visited that site, next time onwards whenever you visit that particular website, data may load up little faster thus loading the webpage faster and easier. This happens because data which are not dynamic will be cached to the Cache memory of the Browser and will use these data to load the website next time onwards.

In Google Chrome, we can easily clear Cache. In fact, Clearing the Cache data might solve the weird issue of ERR_SPDY_PROTOCOL_ERROR.

To Clear Cache in Chrome:

  • Click on the three dots icon

  • Scroll all the way down and click on Advanced Settings.
  • Under the “Privacy and Security “tab, select “Clear browsing data”
  • From the popup, select the time period
  • Click the blue “Clear Data” button
