Relative URL applies wp_make_link_relative function to links (posts, categories, pages and etc.) to convert them to relative URLs. Useful for developers when debugging local WordPress instance on a mobile device (iPad. iPhone, etc.).

More information please visit my site.

For example:

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://192.168.0.1:8080/wp/ on your iPad or other mobile devices without having styles and navigation issue.

Notice: This plugin is mainly used for local development. Haven't tested on a production environment, but it should work, no harm to your sever.
