sass - Compass SCSS font-url configuration issue -

am writing down template use of compass sass here font-mixin makes problem without setting web font.and config file like

http_path = "/" css_dir = "resources/stylesheets" sass_dir = "resources/stylesheets"  images_dir = "resources/images" javascripts_dir = "resources/js" 

and usage of font mixin generated output

@font-face {  font-family: "cabinregular"; src: url('resources/stylesheets/fonts/cabin-regular.eot?#iefix') format('embedded-  opentype'), url('resources/stylesheets/fonts/cabin-regular.ttf') format('truetype'),  url('resources/stylesheets/fonts/cabin-regular.woff') format('woff');  }  

the path correct font won't apply while running html.but if specify http path like

   http_path="/somename/" 

it applies. why won't works without specifying http_path..?

bringing src: url("../fonts/cabin-regular?#iefix"); before main src make working fine

@font-face {   font-family: 'cabinregular';   src: url("../fonts/cabin-regular?#iefix");   src: url("../fonts/cabin-regular?#iefix") format("embedded-opentype"), url("../fonts/cabin-regular") format("woff"), url("../fonts/cabin-regular") format("truetype"), url("../fonts/cabin-regular.svg#cabin-regular") format("svg");   font-weight: normal;   font-style: normal; }
