<para>
The <link linkend="EphyPermissionManager"><type>EphyPermissionManager</type></link> keeps a list of websites and their permissions. For
example, the user may want a certain website to display images but block
cookies and popup windows; this could correspond to three entries in the
<link linkend="EphyPermissionManager"><type>EphyPermissionManager</type></link>.
</para>
<para>
Use <link linkend="ephy-permission-manager-add"><function>ephy_permission_manager_add()</function></link> to set permissions for a website,
<link linkend="ephy-permission-manager-remove"><function>ephy_permission_manager_remove()</function></link> to remove the permissions, and
<link linkend="ephy-permission-manager-test"><function>ephy_permission_manager_test()</function></link> to test them. Note that
<link linkend="ephy-permission-manager-test"><function>ephy_permission_manager_test()</function></link> may return <link linkend="EPHY-PERMISSION-DEFAULT:CAPS"><literal>EPHY_PERMISSION_DEFAULT</literal></link>, which
means the caller might need to find the default permission some other way.
</para>
<para>
The <link linkend="EphyPermissionManager"><type>EphyPermissionManager</type></link> stores a list of site-specific permissions, but not
defaults. For popups, the default permission is determined by the GConf key
/apps/epiphany/web/allow_popups, which in turn determines Mozilla's
dom.disable_open_during_load preference. For cookies, the GConf key
/apps/epiphany/web/cookie_accept determines Mozilla's
network.cookie.cookieBehavior preference. For images, the default is determined
by Mozilla's network.image.imageBehavior preference.
</para>
<para>
The predefined permission types are EPT_COOKIE ("cookie"), EPT_IMAGE ("image")
and EPT_POPUP ("popup"). You can also make up your own type string.
</para>
<para>
Though the word &quot;host&quot; is used in many function descriptions, Mozilla
does not act as one would expect. Always pass a URL to any functions which
need have a &quot;host&quot; parameter. However, the &quot;host&quot; in an
<link linkend="EphyPermissionInfo"><type>EphyPermissionInfo</type></link> is a simple DNS hostname.
