Post revisions enable them to go back to the state prior to making any changes in the articles and undo any modifications done. So how does this post revision feature work? A revision of the post is saved each time a user saves a post or when an auto save feature occurs. The auto save feature saves a post at an interval of 60 seconds and the post is saved as a special revision. The old auto saved revision of a post is replaced by a new auto saved revision.

Browser caching helps in minimizing load on server by reducing the requests sent per page. For instance, by configuring the file headers on files that are static, browsers will cache such files.

The result is that the Web server can now easily answer more than 304 responses and confirming that the file has remained unchanged rather than serving just 200 responses.

You can enable browser caching by downloading and installing a plugin. If you have already installed W3 Total Cache then you need not to install any other plugin because it provides you an option to enable Browser Caching.
