the class TestMIMEChainingAlternate method testAlternateSinglePartDataSource.

//to a writer.

//To make the test easier we will have two callbacks to send to the server to indicate
//the presence of each data source.
//This violates the typical client/server http pattern, but accomplishes the purpose of this test
//and it makes it easier to write.
