After the company's website is always on the back of a few small bugs, but these bugs in the VI after the change to open the Web page but found that there is no change, Google some people said to delete the "/var/cache/nginx" folder, But I found this folder deleted after the restart Nginx still no reaction, and later on StackOverflow saw someone commented that can change the nginx.conf profile, set the Sendfile parameter to OFF (it is turned on by default), Restart Nginx, and then refresh the page, found to return to normal. Also, if you find this problem, you need to make sure that the browser cache data is cleaned up.
