We connected Win8.1 via WebDAV to a folder on our Liferay Folder.
Then we copied a js file into the Windows folder.

Expected result: The js file is accessable/downloadable on the server

Seen result: After downloading the js file via Document portlet the downloaded file is empty (has 0 Byte).
Even in the Windows-Explorer with WEBDav connection the file on the server has 0 Byte.

After adding
com.liferay.portal.servlet.filters.cache.CacheFilter=false
to the portlet-ext.properties (and rebooting) we were able to insert a js file to the folder and download it via Document Portlet or an other WebDAV connection.

The same thing happens with css files.
