-- In addition, you can configure a number of different aspects of Yesod

-- | The base URL for your static files. As you can see by the default

-- A powerful optimization can be serving static files from a separate
-- domain name. This allows you to use a web server optimized for static
-- files, more easily set expires and cache values, and avoid possibly
-- costly transference of cookies on static files. For more information,

-- If you change the resource pattern for StaticR in Foundation.hs, you will

-- To see how this value is used, see urlRenderOverride in Foundation.hs
