#path_to(page_path, options = {}) ⇒ Object

Generates the full path to a given page, taking Rack routers and reverse proxies into account.

Takes an options hash with a single option called uri. Set it to true if you'd like the publicly accessible URI for the path, rather than just the path relative to the site's root URI. The default is false.

path_to(page.abspath, uri: true)
