Relative URL
Relative URL applies the wp_make_link_relative function to links (posts, categories, pages, etc.) to convert them to relative URLs. Useful for developers when debugging local WordPress instance on a mobile device (iPad, iPhone, etc.).
Notice: This plugin SHOULD be used for local development only. I haven’t tested on a production environment; it may work with some issues, like unwanted URLs in RSS feed or sharing URLs are replaced with relative URLs, etc.

Например:
http://localhost:8080/wp/
Will be converted to:
/wp/
And..
http://localhost:8080/wp/2012/09/01/hello-world/
Will be converted to:
/wp/2012/09/01/hello-world/
And..
http://localhost:8080/wp/wp-content/themes/twentyeleven/style.css
Will be converted to:
/wp/wp-content/themes/twentyeleven/style.css
Then after activating this plugin, you can simply access your local instance using http://10.0.1.5:8888/wp/ on your iPad or other mobile devices without having styles and navigation issue.
