Chrome's Offline Cache Mode uses cached files automatically to fix "This webpage is not available" errors
I think we have all been in a situation where a website that we are currently browsing becomes unavailable from one moment to the next. This can happen when an article goes viral for instance and a multitude of the average user count starts accessing the website at the same time. It can also happen if the site is moving to new servers, having hardware issues, experiencing a DOS-attack, when the site has been banned or blocked in the country you are living, and and and..
Most web browsers display an error page of sorts when a website cannot be reached at any given time. The Chrome web browser displays a "This webpage is not available" error page with options to reload the page or click on the more button to retrieve additional information. Reloading may help if the connection error was just a flux, but most of the time it may take minutes, hours and sometimes even days before a site comes back to life.
If you have visited the website before you can retrieve some of the information from Chrome's cache. That's a manual process though and not really something that works too well in most cases.
Google has started to implement a new experimental feature into Canary versions of the web browser that adds an Offline Cache Mode to it. The feature, when enabled, tries to complete the request by displaying the cached version of a page in the browser to the user. As noted before, this works only if the page has been visited before and not if it is a brand new page or site that you never visited before in your life (or since the last clearing of the browser cache).
To activate the new feature do the following:
- Make sure you are running the latest version of Google Chrome Canary. Check for updates with a click on the menu button in the top right corner and the selection of About Google Chrome.
- If you are running the latest version, type chrome://flags in to the address bar and hit the enter key.
- Locate the following entry on the page:
Enable Offline Cache ModeÂ Mac, Windows, Linux, Chrome OS, Android. Reads from web resources when the source is unavailable will be satisfied from available stale cache entries.
- Click on the Enable link underneath it and restart the browser afterwards.
The Offline Cache Mode feature is now activated and will spring in to action automatically when a website cannot be accessed in the Chrome browser. The feature will make its way down in to all other Chrome editions eventually. (via Francois)Advertisement
