SESSION:: commands?

Hi,

 

 

I noticed in a recent Codeshare example (Click here) an iRule referencing a SESSION::data command. Is this specific to SAM? Or 10.x?

 

 

I couldn't a wiki page or any reference to SESSION:: commands on AskF5.

 

 

On a tangential note, can anyone provide details on new iRule functionality in 10.x?

 

 

Thanks,

 

Aaron
