This module enables cookie based authentication for construction area |
This module enables cookie based authentication for construction area |
and is used to control access for three (essentially equivalent) URIs. |
and is used to control access for the following two types of URI |
|
(one for files, and one for directories): |
|
|
<LocationMatch "^/priv.*"> |
<LocationMatch "^/priv.*"> |
<LocationMatch "^/\~.*"> |
<LocationMatch "^/priv.*/$"> |
<LocationMatch "^/\~.*/$"> |
|

Whenever the client sends the cookie back to the server, |
if the cookie is missing or invalid, the user is re-challenged |

in the URL match those in the expected environment. If so, return |
two element list ($ownername,$ownerdomain). Else, return null string. |
three element list ($ownername,$ownerdomain,$ownerhome). |
If 'setpriv' is set to 'setpriv', it actually assigns the privileges. |
|
|
Otherwise return the null string. |
|
|
|
If second argument 'setpriv' is true, it assigns the privileges, |
|
and returns the same three element list, unless the owner has |
|
blocked "ad hoc" Domain Coordinator access to the Author Space, |
|
in which case the null string is returned. |
