所以我拿出了原来的cURL代码，我已经复制了一些Zend的具体代码从一个不同的项目，这似乎工作的大部分（不是真的确切为什么...）。我遇到的唯一的其他问题处理CoSign（http://cosign.sourceforge.net/）和使用代理cookie。感谢那些提供答案的人！

So I took out the raw cURL code I had and copied in some Zend specific code from a different project, and that seemed to work for the most part (not really sure why...). The only other problems I've run into deal with CoSign (http://cosign.sourceforge.net/) and using proxy cookies. Thanks to those who offered answers!
