Note

InMemoryResponse is a basic type of response. There are several response types that are wrappers to the InMemoryResponse.

For example, NotFoundReponse sets the appropriate headers and response code for an InMemoryResponse to send an error 404 response to the client.

You can look at the net.liftweb.http.LiftResponse to see every type of response provided by Lift.

The third parameter is a list of HTTP cookies, which we will pass a Nil value—an empty list—because we don't care about cookies in this case. We passed 200 as the last parameter to define the HTTP response status code.

Now that we know how to build an HTTP response to serve an RSS feed, let's learn how to build the feed content.

To build the feed content, we created the method getClients, which builds an XML object using some helper methods. These helper methods format the date and mapping of our list of clients to build XML item blocks; each client is an item block. So, after iterating the list of clients, it returns the XML that will be used as the parameter when calling the toRss method.
