求助curl?

有谁有过curl编程的经验，英文我看得有许多不明白
有什么好的中文相关网站推荐，谢谢

CURLOPT_FOLLOWLOCATION
A non-zero parameter tells the library to follow any Location:
header that the server sends as part of an HTTP header
CURLOPT_UNRESTRICTED_AUTH
A non-zero parameter tells the library it can continue to send authentication (user+password)
when following locations even when hostname changed
This option is meaningful only when setting CURLOPT_FOLLOWLOCATION

呵呵，帮我翻译一下啊
