The arguments are: ``app`` The WSGI application or middleware chain. ``codes`` A dictionary of integer status codes and the URL to be displayed if the response uses that code. For example, you might want to create a static file to display a "File Not Found" message at the URL ``/error404.html`` and then use ``forward`` middleware to catch all 404 status codes and display the page you created.

If you don't need the full power of this middleware you might choose to use the simpler ``forward`` middleware instead. The arguments are: ``app`` The WSGI application or middleware chain. ``mapper`` A callable that takes a status code as the first parameter, a message as the second, and accepts optional environ, global_conf and named argments afterwards. It should return a URL to forward to or ``None`` if the code is not to be intercepted. ``global_conf`` Optional default configuration from your config file. If ``debug`` is set to ``true`` a message will be written to ``wsgi.errors`` on each internal forward stating the URL forwarded to. ``**params`` Optional, any other configuration and extra arguments you wish to pass which will in turn be passed back to the custom mapper object. Here is an example where a ``404 File Not Found`` status response would be redirected to the URL ``/error?code=404&message=File%20Not%20Found``. This could be useful for passing the status code and message into another application to display an error document: .. code-block:: python from paste.errordocument import StatusBasedForward from paste.recursive import RecursiveMiddleware from urllib import urlencode def error_mapper(code, message, environ, global_conf, kw) if code in [404, 500]: params = urlencode({'message':message, 'code':code}) url = '/error?'%(params) return url else: return None app = RecursiveMiddleware( StatusBasedForward(app, mapper=error_mapper), ) cKsm|dkri}n|r<tj|jdt|_n t|_||_||_||_||_ dS(Ntdebug( RRtasbooltgettFalseR/t applicationtmapperR tparams(RRR4R R5((s7/usr/lib/python2.7/site-packages/paste/errordocument.pyRs  !    csgg}dfd}j|}r|t|dr[|jnfd}td|n|SdS(Ncs|jd}yt|d}Wn1ttfk rVtdt|dnXdj|d}j||jj }|dkpt |t std|n|rj |||ggj S|||SdS(Nt is@StatusBasedForward middleware received an invalid status code %sisiExpected the url to internally redirect to in the StatusBasedForward mapperto be a string or None, not %r(R&Rt ValueErrorRt ExceptionRtjoinR4R R5RRtstrR(RRRt status_codeRR tnew_url(R RR R(s7/usr/lib/python2.7/site-packages/paste/errordocument.pytchange_responses,  tclosec s4t|dddddddddS(NRiiRRi(R(R(R(s7/usr/lib/python2.7/site-packages/paste/errordocument.pytfactorys%R?(RR3thasattrR>R(RR R twriterR=tapp_iterR?((R RR Rs7/usr/lib/python2.7/site-packages/paste/errordocument.pyR,s N(R-R.t__doc__RRR,(((s7/usr/lib/python2.7/site-packages/paste/errordocument.pyR^s4 cKsti}xX|jD]J\}}yt|}Wn!tk rRtd|nX||| Error %(code)s
