I'm using HTTP Watch through IE (I'm somewhat limited in what I can use in my corporate enviornment) to capture the data from the form submission -- I assume that HTTP Watch will capture the same data as LiveHttpHeaders. Here is the post data as captured by HTTP Watch:

paramater       value           size
login_password    passoword    18    
login_username    username    18    
prefLanguage    00000000    21    
submit        Log On            13

and here is the only cookie (which doesn't seem necessary since I can log in with cookies turned off) 
Name    Direction Value Path    Domain          Duration   
C0    Sent      apc    /    .192.168.0.2    (Session)

HTTP Only    Secure 
No         Yes

and, finally, here is the header information
