jtheboywonder -> URL with and without readable information (27.Jan.2011 2:55:37 PM)

I have two questions really from the group:

1. Why is it that for some if not most communication you get a full URL string with CMD, USER, DEVICEID and DEVICETYPE, but on some connections you get a random (I am assuming encrypted or something) set of characters similar to kqcHjOrfaGqNims4ElJneBDcZLdYCU1A= ??? The username still shows, source and destinations still show, and activity still happens, but why is there no insight (unless you read code) on these connections? I am assuming this is a code reference because i can see a couple of patters such as CU1A at the end of the strings and what appears to be an encoded username at the beginning, but how would you view this? Am I overlooking the obvious?

2. With that in mind, I think I am getting an error by certain devices when they attempt to make a connection but wait too long (maybe this is a device setting) all of which have a higher than average processing time (although there are longer connections that are successful) and all of which have the randomized character sting as described above, and give a failed connection attempt of 10054 as listed below? Any ideas on the source of the error and how to see if it really is a problem or an expected behavior?
