阅读更多关于 Nginx fails to load css files

问题 I\'ve recently decided to switch from Apache2 to Nginx. I installed Nginx on my CentOS server and setup a basic configuration. When I tried to load my site in browser (FF/Chrome) I noticed that css file is not loaded. I checked the error console and saw this message: Error: The stylesheet http://example.com/style.css was not loaded because its MIME type, \"text/html\", is not \"text/css\". I checked Nginx configuration and everything seems to be fine: http { include /etc/nginx/mime.types; ...

问题 When creating email messages you are supposed to set the Content-Type to multipart/alternative when sending HTML and TEXT or multipart/mixed when sending TEXT and attachments. So what do you do if you want to send HTML, Text, and attachments? Use both? 回答1: I hit this challenge today and I found these answers useful but not quite explicit enough for me.

Let\'s say you want to dish these files out via a web page and have the client automatically open the correct application/viewer. Assumption: The browser figures out which application/viewer to use by the mime-type (content-type?) header in the HTTP response. Based on that assumption, in addition to the bytes of the file, you also want to save the MIME type. How would you find the MIME type of a file? I\'m

问题 I have a page that allows the user to download a dynamically-generated file. It takes a long time to generate, so I\'d like to show a \"waiting\" indicator. The problem is, I can\'t figure out how to detect when the browser has received the file, so I can hide the indicator. I\'m making the request in a hidden form, which POSTs to the server, and targets a hidden iframe for its results. This is so I don\'t replace the entire browser window with the result. I listen for a \"load\" event on the
