Htaccess – Prevent Unauthorized Directory Browsing

Prevent unauthorized directory browsing by instructing the server to serve a “xxx Forbidden – Authorization Required” message for any request to view a directory.

For example, if your site is missing it’s default index page, everything within the root of your site will be accessible to all visitors. To prevent this, include the following htaccess rule:

# disable directory browsing
Options All -Indexes

Conversely, to enable directory browsing, use the following directive:
# enable directory browsing<br /> Options All +Indexes

Likewise, this rule will prevent the server from listing directory contents:
# prevent folder listing<br /> IndexIgnore *

And, finally, the IndexIgnore directive may be
used to prevent the display of select file types:

# prevent display of select file types<br /> IndexIgnore *.wmv *.mp4 *.avi *.etc
