- The view restriction is not suitable for very sensitive content since there is a way to circumvent the read access restriction.
- Read access restriction only works if the view script is authenticated, that means that users need to log on also just to read topics. TWiki Installation has more on basic authentication based on the
.htaccess file.

- There is a workaround if you prefer to to have unrestricted access to view topics located in normal webs, and to authenticate users only for webs where view restriction is enabled:

-
- Leave the
view script non authenticated in the .htaccess file.
- Enable the
$doRememberRemoteUser flag in wikicfg.pm as described in TWiki Authentication. TWiki will now remember the IP address of an authenticated user.
- Copy the
view script to viewauth (or better, create a symbolic link)
- Add
viewauth to the list of authenticated scripts in the .htaccess file.

- If you enable view restriction for a web, it is recommended to restrict search "all webs" from searching this web. Enable this restriction with the
NOSEARCHALL variable in its WebPreferences, like:
- It is not recommended to restrict view access to individual topics since all content is searchable within a web.

The above schema can lock completely a topic in case of a typing error of the ALLOWTOPICCHANGE setting (see UnchangeableTopicBug ). To avoid this:
- set the
$superAdminGroup variable in TWiki.cfg to the name of a group of users that are always allowed to edit/view topics. E.g.:
