Allow all access for certain extensions with certain methods

Server Config
1

Hi,

I have a virtual host configured with authmysql. I now want to configure it in such a way that files with certain extensions (doc, docx, xls, etc…) don’t require authentication for certain http methods (PROPFIND HEAD OPTIONS).

I am currently using:

<LimitExcept PROPFIND HEAD OPTIONS>
require valid-user
</LimitExcept>

This way no valid-user is required for these methods, but it is for all files/folders. I only want it to be for the given extensions.
