How to check if a protocol is https?

Hello Community,

 

Does anyone know what syntax is needed to check if a protocol is https or http? I"m currently sharing a IRule with both https and http Virtual Servers

 

and only want to execute certain IRules if the check of the protocal is true or false.

 

Any help is fully appreciated.

 

Thanks.

 

Regards,
