[Pki-devel] [PATCH] 655 Replaced legacy HttpClient.

The ConfigurationUtils and CertUtil have been modified to use PKIConnection which uses Apache HttpClient instead of the legacy custom HttpClient. The POST request content is now created using MultivaluedMap. The PKIConnection has been modified to provide a get() method to send an HTTP GET request. The post() method was modified to accept a path parameter. https://fedorahosted.org/pki/ticket/342 -- Endi S. Dewata
