Hi,I have a simple question.  
What´s the best way to detect if the client has session support?.  
I want to hide some functions of my web application to robots(seo stuff)  
and I would need to check in my controllers if the client has session  
support, if the client supports sessions I initialize some variables and  
then use it in my views if not(most likely it´s a robot) this functions  
are hidden.  
Another option would be to use javascript in my views to show the “only  
human functions” but I would prefer to keep it in the controller side.

Some suggestions?
