Have you ever wondered why the new Microsoft 2007 Word file type (.docx) can not be downloaded directly from your Apache server? Well, the answer is because it doesn’t recognize what kind of application type it is, therefore it can’t send the correct header information to your browser. Fortunately, the fix for this is rather simple with Apache. Just add these application types for MS Word to your server’s httpd configuration (httpd.conf or apache2.conf) and files will start downloading like magic.
