WP-URLCache allows you to use a shortcode to locally cache outgoing links in your posts and pages.
- Use WordPress’ builtin plugin installation system located in your WordPress admin panel, labeled as the "Add New" options in the "Plugins" menu to upload the zip file you downloaded
- Extract the zip file and upload the resulting "wp-urlcache" folder on your server under
wp-content/plugins/
.
All you need to do after that is navigate to your blog’s administration panel, go in the plugins section and enable WP-URLCache.
In order to personalize the available options, check in WordPress' "Misc" section under "Settings" (options-misc.php).

"Installing Plugins" article on the WordPress Codex.
