Httpcontext.current.cache returns "object not reference not set to an instance" error inside the c# class library

Hi,

I am using an existing class library that uses Httpcontext.current.cache for my c# class library. My problem is I want to use that object but I am getting "object not reference not set to an instance" error because the httpcontext is not present.
I want to prevent those httpcontext.current.cache from executing so the object won't return an error. My question is, is there a way to do that?

Thanks
George
