It does this by calling the C{init} function of the L{mimetypes} module. This will have the side effect of modifying the global MIME types cache in that module. Multiple file locations containing mime-types can be passed as a list. The files will be sourced in that order, overriding mime-types from the files sourced beforehand, but only if a new entry explicitly overrides the current entry. @param mimetype_locations: Optional. List of paths to C{mime.types} style files that should be used. @type mimetype_locations: iterable of paths or L{None} @param init: The init function to call.

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 'http://server/FILE' to a resource created as File('/tmp'), then http://server/FILE/ will return an HTML-formatted listing of the /tmp/ directory, and http://server/FILE/foo/bar.html will return the contents of /tmp/foo/bar.html . @cvar childNotFound: L{Resource} used to render 404 Not Found error pages. @cvar forbidden: L{Resource} used to render 403 Forbidden error pages. @ivar contentTypes: a mapping of extensions to MIME types used to set the default value for the Content-Type header.

For example, if C{ignoredExts} is C{(".bar",)} and C{path} is a directory containing a file named C{"foo.bar"}, a request for the C{"foo"} child of this resource will succeed with a L{File} pointing to C{"foo.bar"}. @param registry: The registry object being used to handle this request.

This method checks that the resulting range overlaps with the resource being served (and so has the value of C{getFileSize()} as an indirect input). Either but not both of start or end can be L{None}: - Omitted start means that the end value is actually a start value relative to the end of the resource. - Omitted end means the end of the resource should be the end of the range. End is interpreted as inclusive, as per RFC 2616. If this range doesn't overlap with any of this resource, C{(0, 0)} is returned, which is not otherwise a value return value. @param start: The start value from the header, or L{None} if one was not present. @param end: The end value from the header, or L{None} if one was not present. @return: C{(offset, size)} where offset is how far into this resource this resource the range begins and size is how long the range is, or C{(0, 0)} if the range does not overlap this resource.

This method checks if the request is satisfiable and sets the response code and Content-Type and Content-Length headers appropriately. The return value, which is a little complicated, indicates which parts of the resource to return and the boundaries that should separate the parts. In detail, the return value is a tuple rangeInfo C{rangeInfo} is a list of 3-tuples C{(partSeparator, partOffset, partSize)}. The response to this request should be, for each element of C{rangeInfo}, C{partSeparator} followed by C{partSize} bytes of the resource starting at C{partOffset}. Each C{partSeparator} includes the MIME-style boundary and the part-specific Content-type and Content-range headers. It is convenient to return the separator as a concrete string from this method, because this method needs to compute the number of bytes that will make up the response to be able to set the Content-Length header of the response accurately. @param request: The Request object. @param byteRanges: A list of C{(start, end)} values as specified by the header. For each range, at most one of C{start} and C{end} may be L{None}. @return: See above.
