Heya,

 

I had a brain fade, Piotr is correct regarding http profile being required for cookie persistence.

 

If you are seeking to encrypt your persistent cookie, that can be configured from within the cookie persistence profile. If you wish to encrypt other cookies then you can specify those particular cookies in the HTTP profile.

hi Piotr,

 

Thank you very much for your response..This clarified me .Please find the bottom line of the my query and let me know if I can do it.

 

for suppose I enabled cookie encryption in the http_prod http profile.

 

case 1: for VIP with only http_prod profile(no cookie profile) , this does nothing I didnt map any cookie persistence profile to it.no stickyness provided as there is no cookie persistence.

 

case 2: for VIP with both http_prod and cookie profiles, as I enabled cookie encryption in the http profile, the LTM starts encrypting and decrypting the cookie between Client and itself and provide stickyness

 

Please let me know the above cases are correct.

 

Thanks again. Sai
