Microsoft Office 2007 New Formats and your Apache server



If you upload those new fancy-shmancy file formats to your web server – namely .docx, .pptx and .xlsx – and you are running Apache; chances are that your web server doesn’t know how to serve those files because they are unknown file formats. Your browser may try to download them as a .zip file (IE) or just display the binary format (Firefox) which ends up looking like jibberish with some XML data.

It’s relatively easy to fix this problem, you just need to tell apache how to handle those files.

Find the file mime.types, this may be in /etc/ or in /etc/httpd/conf/.

Add the following line to this file:

1
application/vnd.openxmlformats       docx pptx xlsx

In one line:

1
echo "application/vnd.openxmlformats       docx pptx xlsx" >> /etc/httpd/conf/mime.types

Restart both Apache and your web browser. Clearing the cache doesn’t work (I learned the hard way :))

Your file should now be downloaded properly to your PC.
