Date Wed, 29 Apr 2009 16:12:21 GMT
Author: rpluem

New Revision: 769809

URL: http://svn.apache.org/viewvc?rev=769809&view=rev
Log:
* Improve and simplify the implementation of SSLProxyCheckPeerExpire by
  directly using X509_get_notBefore(), X509_get_notAfter() and
  X509_cmp_current_time().
  Thanks to jorton for the pointer.
