Configuring Flash Communication Server 35
• <Order> specifies the order in which to evaluate the preceding <Allow> and <Deny> tags. It
can be set to either
Deny,Allow (the default) or Allow,Deny.
When
Deny,Allow is specified, the server allows the user specified in <Username> to connect
from any host that is not included in the
<Deny> tag or is included in the <Allow> tag. Access
is denied from any host that is included in the <Deny> tag and is not included in the <Allow>
tag.
When
Allow,Deny is specified, the server allows the specified user to connect only from hosts
that are included in the
<Allow> tag and are not included in the <Deny> tag. Access is denied
from any host that is not included in the
<Allow> tag or is included in the <Deny> tag.
• <Adaptor> specifies the name of an adaptor in its name attribute. It is a container for one or
more
<VirtualHost> tag groups that specify the virtual host administrators for each virtual
host in the adaptor. You may specify multiple adaptors by adding additional <Adaptor> tag
groups to the Server.xml file.
• <VirtualHost> specifies the name of a virtual host in its name parameter. It is a container for a
<UserList> tag that defines administrators for the virtual host. The default value is
<VirtualHost name="_defaultVHost_"> because the default virtual host included with the
server is named _defaultVHost_. The name parameter tells the server which virtual host the
enclosed
<UserList> tag refers to. A virtual host is defined on the server simply by having a
directory inside the adaptor directory that contains a valid Vhost.xml file. If you have more
than one virtual host on one or more adaptors on the server, you specify their administrator
information with separate sets of
<VirtualHost> tags in the Server.xml file.
• The <UserList> tag is a container for one or more <User> tag groups.
• The next <User> tag specifies the name of a virtual host administrator in its name parameter.
The user name can contain only alphanumeric characters. The <User> tag contains the same
set of password and host-permission tags as the
<User> tag in the earlier <Server> tag, but this
<User> tag specifies the administrator user information for the virtual host tag that contains it.
Virtual host administrators can only perform administration tasks relating to the applications
running on their own virtual host. Administration tasks relating to the virtual host itself must
be performed by a server administrator.
You can specify multiple administrator users for a single virtual host by including additional
sets of
<User> tags in the <UserList> tag for the virtual host.
Only users defined here and in the earlier
<User> tag (in the <Server> section) are allowed to
connect to the Administration Console. (For more information, see Using the Administration
Console.) Normally, you add and edit virtual host administrator information with the
Administration Console. If you edit user names directly in the Server.xml file, you must use
only valid XML in the
<User> and <Password> tags.
By default, only the Administration Console requires a valid administrator user name and
password when connecting to the server. Other client applications do not require any user
name or password unless they are explicitly programmed to do so by the author.
• The <Password> tag specifies the password for the <User> tag that contains it. Its format is the
same as the
<Password> tag inside the earlier <Server> tag.
• The <Allow> tag inside the <VirtualHost> tag works the same way as the <Allow> tag inside
the earlier
<Server> tag, but applies only to the <User> tag that contains it.
• The <Deny> tag inside the <VirtualHost> tag works the same way as the <Deny> tag inside
the earlier
<Server> tag, but applies only to the <User> tag that contains it.
