Ever been knocked offline right before you get to read a story on the web? If Google has its way, you won't be left high and dry in these situations for much longer. The company has posted a test release of its Chrome browser that include a "show saved copy" button on the connection error page. Click that and you should see the last cached version of whichever site you were trying to reach. There's no guarantee that this offline support will reach polished versions of Chrome, but it would be surprising if that didn't happen -- the feature would be handy for both offline directions and reading material on long flights. If you can't wait for a complete release, you can visit the source link to grab the Canary build and try the button yourself.
