class UnknownFileTypeServlet(WebKit.HTTPServlet.HTTPServlet, MiscUtils.Configurable.Configurable)
`` | `Servlet for unknown file types. Normally this class is just a "private" utility class for WebKit's purposes. However, you may find it useful to subclass on occasion, such as when the server side file path is determined by something other than a direct correlation to the URL. Here is such an example: from WebKit.AppServer import globalAppServer from WebKit.UnknownFileTypeServlet import UnknownFileTypeServlet import os class Image(UnknownFileTypeServlet): imageDir = '/var/images' def filename(self, trans): filename = trans.request().field('i') filename = os.path.join(self.imageDir, filename) return filename`

Taken from Application's 'UnknownFileTypes' default setting.` filename(self, trans) `Return the filename to be served. A subclass could override this in order to serve files from other disk locations based on some logic.` lastModified(self, trans) redirectSansAdapter(self, trans) `Redirect to web server. Sends a redirect to a URL that doesn't contain the adapter name. Under the right configuration, this will cause the web server to then be responsible for the URL rather than the app server. This has only been test with "*.[f]cgi" adapters. Keep in mind that links off the target page will *not* include the adapter in the URL.` respondToGet(self, trans) `Respond to GET request.

Returns a boolean that controls whether or not the content served through this servlet is cached. The default behavior is to return the CacheContent setting.
