Connection Configuration
Open the configuration file fcserver.xml
In the Connection Section, you can set two servers and listen to two ports.
primary-server
secondary-server
There are four reasons as to why there is a second server port option. They are listed below:
1. Any version before Flash Player 7 only allows access on a high port (1024-65535) due to security reasons, while a low port is forbidden. If you are okay with high port you will not need to set secondary-server. However if you need to set port lower than 1024, you will need a secondary-server.
2. If the port of your primary-server is lower than 1024 like 80, then only users with Flash Player 7 or newer versions will be able to access the chat while users with flash player 6 can't.
In this case a secondary-server will be necessary. The port for the secondary server should be greater than 1024, which will allow users with an earlier version of Flash Player to access chat.
3. If you are going to set a high port for your primary-server, then usually you will not need a secondary-server. You will be able to leave the option as default: enable="off".
4. Using two servers with two ports is just a temporary solution while some users are still using Flash players earlier than version 7.
When Flash player 7 or higher version becomes mainstream, we will take off the secondary-server for future versions of 123 Flash Chat.

To modify the Parameters, please refer to the table below
Parameter |
Type |
Default Value |
Description |
port |
Number |
51127 |
The server port must be identical with the port value in client.xml. |
ip |
String |
* |
Set the Server address.
A default "*" means the chat server will bind to all IP addresses of your server.
The host value in client.xml can be a random IP address or any domain name which points to this IP address. Either way, clients will be able to connect to the server.
If you set IP address of the server to the specific IP address of your server, then the chat server will only bind to this IP. This will mean that in client.xml, to connect the chat server, you can only use this specific IP address or the domain name which points to this IP address.

Type |
Default Value |
Description |
port |
Number |
35555 |
The server port must be identical with the port value in client.xml. |
ip |
String |
* |
Set the Server address.
A default ¡°*¡± means the chat server will bind to all IP addresses of your server.
The host value in client.xml can be a random IP address or any domain name which points to this IP address. Either way, clients will be able to connect to the server.
If you set IP address of the server to the specific IP address of your server, then the chat server will only bind to this IP. This will mean that in client.xml, to connect the chat server, you can only use this specific IP address or the domain name which points to this IP address |
enable |
String |
On |
Enable or disable the http server |
documentRoot |
String |
../client |
The directory out of which you will serve your documents. By default, all requests are taken from <123flashchat installed directory>/client directory. |
maxUPLoadSize |
numbers |
1024 |
Setting the max file can be uploaded to the server, if the value less than or equals to 0, this means the server will not accept any upload files. |
cross-domain-policy
123 Flash Chat Server start using the cross-domain-policy to ensure security.
<cross-domain-policy>
<allow-access-from domain="*" />
</cross-domain-policy>
By default it permits access to the connection originating from any domain.
To limit access from a specific domain name, you can configure your server in the following way:
<cross-domain-policy>
<allow-access-from domain="www.mydomain.com" />
<allow-access-from domain="*.mydomain.com" />
</cross-domain-policy>
To allow multiple domain names to be accessible you can configure your server in the following way:
<cross-domain-policy>
<allow-access-from domain="www.myfriendsdomain.com" />
<allow-access-from domain="*.mydomain.com" />
<allow-access-from domain="11.22.33.44" />
</cross-domain-policy>
max-connections-per-ip
<!-- max-connections-per-ip
Connection limit of each IP. By default it is "10".
If configure it to "0", then one IP can login unlimited connections, this can be used for performance test. -->
<max-connections-per-ip>10</max-connections-per-ip >
In current version, the cross-domain-policy is now enhanced in this way:
not only all connections originating from domain which is not in the allow-access list is forbidden, those connections originating from local computer by launching SWF file are now denied, too.
Only connections from allow-access list can access chat.
(Of course you can set it to permit access from any domain.)
