The LLP client and server components described in these sections are included for legacy backward compatibility only. They are not supported for new application development. If you are developing a new application, use Iguana as the transport mechanism for sending messages over LLP, and use the Iguana plugin API to define an interface between your application and the Iguana server. For more details on using plugins in Iguana, see Working With Plugins. For reasons why you should use Iguana instead of Chameleon for your LLP solution, see Why Choose Iguana Over Chameleon?.

This is a helper object used by the LlpServer object. It is passed with each event raised by the LlpServer object and has properties on it to allow the called event to know which client raised an event and methods to send messages back or disconnect from the client.

Four methods on the LlpConnection class are of particular interest:

• getRemoteHostName: If possible, resolves the remoteIpAddress to the host name using the operating system. If no host name resolution is possible, this will return 'unknown'.
• getRemoteIpAddressAsString: Provides the IP address of the client as a string.
• transmitMessage: Sends a message to the client, prefixed and postfixed by the current headerBlock and trailerBlock characters.
• disconnect: Attempts to gracefully disconnect from the Server.

	getRemoteHostName Method The first time that this method is called, it blocks until the name is resolved. As a result, if you make the call in the context of your message loop, your application will appear to freeze for a few seconds while it performs a synchronous blocking DNS lookup call. This issue will be most noticeable on a machine with a misconfigured host lookup configuration.
