From 5581143bee602dbd5417f532f2b483e58d0a4269 Mon Sep 17 00:00:00 2001 From: Brion Vibber Date: Wed, 28 Oct 2009 15:29:20 -0400 Subject: Rebuilt HTTPClient class as an extension of PEAR HTTP_Request2 package, adding redirect handling and convenience functions. Caching support will be added in future work after unit tests have been added. * extlib: add PEAR HTTP_Request2 0.4.1 alpha * extlib: update PEAR Net_URL2 to 0.3.0 beta for HTTP_Request2 compatibility * moved direct usage of CURL and file_get_contents to HTTPClient class, excluding external-sourced libraries * adapted GeonamesPlugin for new HTTPResponse interface Note some plugins haven't been fully tested yet. --- extlib/HTTP/Request2.php | 844 +++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 844 insertions(+) create mode 100644 extlib/HTTP/Request2.php (limited to 'extlib/HTTP/Request2.php') diff --git a/extlib/HTTP/Request2.php b/extlib/HTTP/Request2.php new file mode 100644 index 000000000..e06bb86bc --- /dev/null +++ b/extlib/HTTP/Request2.php @@ -0,0 +1,844 @@ + + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * + * * Redistributions of source code must retain the above copyright + * notice, this list of conditions and the following disclaimer. + * * Redistributions in binary form must reproduce the above copyright + * notice, this list of conditions and the following disclaimer in the + * documentation and/or other materials provided with the distribution. + * * The names of the authors may not be used to endorse or promote products + * derived from this software without specific prior written permission. + * + * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS + * IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, + * THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR + * PURPOSE ARE DISCLAIMED.
