Hi Kenneth,
   
      Thanks for the follow-up note and additional pointers.  The point is that 
there is only one relevant private key in all of these transactions (the 
Server1 web-server private key).  Also, even though there is communication 
between two servers, in reality one of the servers (i.e. Server2) is acting as 
a HTTPS client to the other (i.e. the web server on Server1).
   
       Our fundamental question is:  Can we depend on 'tshark' to perform the 
SSL decryption given our series of steps or is that something too much to 
expect?
   
       Best regards,
   
  Vijay

Verify that your private keys are valid on all tiers... isolate the 
transaction: 
4. Server1 -> Server2 (response to request in Step 3). 

Capture just this traffic -- without examining your capture indetail I am 
assuming that the keys are either not valid on server2, or that you are missing 
the server to server handshake. The only commercial program I have experience 
with is OPNET ITguru and it uses wireshark as its backend so this is all the 
same area. 

If you are missing the server to server handshake you may need to force the 
handshake to reoccur, is this a production server? 
There is more info on the handshake process here: 
http://docs.sun.com/source/816-6704-10/ssl_overview.html#13602 

I am reading your description of the steps as this is inter server 
communication, is that what happens or is this still going back to the client?

I see amazon has 5 copies in stock right now.
