Its constructor takes a file path. Alternatively, you can give a directory path to the constructor. In this case the resource will represent that directory, and its children will be files underneath that directory. This provides access to an entire filesystem tree with a single Resource. If you map the URL C{http://server/FILE} to a resource created as File('/tmp'), C{http://server/FILE/foo/bar.html} will return the contents of C{/tmp/foo/bar.html} . c C s% t t d � s t � t _ n t j S( Nt _sharedContentTypes( t hasattrR@ t loadMimeTypesRA ( R ( ( s /opt/cpanel-ccs/txweb2/static.pyt _getContentTypes� s t gzips .gzt bzip2s .bz2t indexs index.htmls index.htms index.trps index.rpys text/plainc C s� t t | � j � i | _ t | t � r7 | | _ n* t | t � sR t d � � t | � | _ | | _ t | � | _ | d k r� t g | j � D] \ } } | j � | f ^ q� � | _ n | d k r� | | _ n d S( s+ Create a file with the given path. s This should be a string.N( R% R@ R6 t putChildrent isinstancet FilePatht fpt strt AssertionErrort defaultTypet listt ignoredExtsR t dictt itemst lowert processorst indexNames( R t pathRN RP RT RU t keyR.
