This is base64 encoded, please see
xmlBlaster/src/java/org/xmlBlaster/protocol/http/appletproxy/AppletServlet.java
about the implemented protocol.

I have commited an extended EncodableData.java which you can use (get it
from svn):

java org.xmlBlaster.util.EncodableData
AAAAAAAXZHVtbXlUb0NyZWF0ZUFTZXNzaW9uSWQAAAAAABBPSy0xMTI3NzIyMTIzMDYy

'AAAAAAAXZHVtbXlUb0NyZWF0ZUFTZXNzaW9uSWQAAAAAABBPSy0xMTI3NzIyMTIzMDYy'
-> 'dummyToCreateASessionIdOK-1127722123062'
