how to serve manifest files, ie. .appcache files wit hunchentoot?

(mime-type #p"path/to/anifest/file")

>nil

nil

is there a way to do?

or is it jsut enough to proxy with apache or nginx front and configure those to serve manifest files, as it is noted in w3schools html5- appcache topic?

before i try myself, just asked to bring it to attention for possible renewing improvements to the hunchentoot.
