I am a beginner for nginx development and nginx is really tough for me. Now I'm developing a distributed mp4 system getting used of the mp4_module in nginx. What I need to do is to whenever a client ask for an mp4 file, the server will download the file from other servers to local and then process the file. The question is how to download files in nginx. The protocol can http. I've try using libcurl. However, whenever I called the functions in libcurl, some errors occur. Here's the error.log.

I wonder what the last message means and I am looking for any other better way to do it. Thank you very much.
