Hi,

Im new in Nginx. After read few articles, i think Nginx is faster than apache (if i'm not mistaken)

Currently we're developing a project in apache. But when we set up a "user acceptance test", our clients complain that our site is running slow. So we migrate to nginx, everything seems to be ok, but when i want to upload a file (using cloudinary), we never success. Previously when we're in apache, this feature is ok.

we host our site in AWS

here are the log file..

any thoughts will be very helpful
