This complicates adding new status codes. It should be possible to constrain the number of status groups the Frontier has to know and then let the processors decide which group a new status code falls into. Possible status groups are:</p><p>successful</p><p>failure</p><p>disregard</p><p>retry immediately</p><p>retry after any prerequisite</p><p>retry at some later time</p></div><div class="navfooter"><hr><table summary="Navigation footer" width="100%"><tr><td align="left" width="40%"><a accesskey="p" href="refactor_HTTPRecorder.html">Prev</a> </td><td align="center" width="20%"><a accesskey="u" href="futures.html">Up</a></td><td align="right" width="40%"> <a accesskey="n" href="release_numbering.html">Next</a></td></tr><tr><td valign="top" align="left" width="40%">1.
