Thank you for your quick response. I did try the parenthesis and that seemed to help...although, I think, I am conerned about having 'NOT' for both of the matchclasses be the true condition now...versus just a NOT for the first statment. But, I'll be able to test that further once I get by the next problem.

 

 

When I started logging the data from the 'rule' I found that the SSLClientCipher header is only returning

 

 

RC4-MD5,

 

 

versus the entire string. When I print this out via the log statement I am doing the following:

 

 

log "Matchclass True: [HTTP::header SSLClientCipher]"

 

 

Now I'm wondering whether the rule to set this is really working as expected since the SSLClientCipher string should be much longer based on what I was being returned in 4.5.
