Example capture file

Here is a sample capture file that will exhibit the issue. There is an SSL
session between 192.168.200.2 and 6.0.0.1 at port 443. The 192.168.200.2 device
uses lots of small SSL Records. Many per TCP packet.

Here is the private key for 6.0.0.1. Add a rule for 6.0.0.1 port 443 decode as
http. Then try to use the follow SSL stream option.

You can also download the capture directly from CloudShark.

Note that the SSL stream from 6.0.0.1 -> 192.168.200.2 looks fine. Its only the
SSL stream from 192.168.200.2 -> 6.0.0.1.

I will add two more attachments that show what the data looks like and what it
should look like when follow SSL is used.
