Plugin Description
As the internet grows older, link rot is becoming a serious problem. Dead links hurt your SEO ranking and reduce the value of your “evergreen” content.
CacheHero eliminates link rot on your site by locally caching any external links in your site’s pages and posts. If an external link goes down, CacheHero will automatically rewrite the link URL to its cached version.
CacheHero is designed to be “set and forget”. It will work immediately upon installation and activation, but there are also some advanced settings such as blacklists of domains and extensions that you want the plugin to ignore (e.g. large video files).
PhantomJS Integration
By default, CacheHero only caches the basic HTML of a linked page (unless the link is a direct link to a filetype such as PDF or JPG). If you want to capture a more visually faithful version of the cached page, CacheHero can work with an installed PhantomJS binary to take screenshots of HTML pages. If enabled, visitors will be given the option to view either the CacheHero HTML version or the PhantomJS screenshot.
Setting up PhantomJS integration in 3 easy steps:
- Download the appropriate PhantomJS binary (phantomjs.org) for your hosting platform.
- Install the binary on your server and make sure it is executable by the web process that runs PHP (if on Linux, running
chmod a+x /path/to/phantomjs along with making sure that the server user can run the binary should be sufficient)
- Enter the absolute path (the ‘pwd’ command may be useful) to the binary on the CacheHero settings page
