Setting variables based on calling VS

Hello,

 

 

I’m wondering if it’s possible to set variables by determining the calling virtual server. For example, If the calling VS is named App1, I want to set a variable to "App1". If the calling VS is App2, then I’d like to set it to "App2", etc. Is this possible? if so, how?

 

 

Thank you,
