What are the technologies that underpin scripting languages?

I have to write a paper and the document given to me said the following:

"How the technologies that underpin the scripting languages and enable their integration with the Web server have changed and how they have improved the performance of Web applications".

I am somewhat lost. I can not really work out what i should write. So my question is how do you understand the sentence above given the fact that the paper in general is about the evolution of Server-Side technologies and Scripting languages? I was going to write about CGI (Common Gateway Interface) and ASP but i am not sure it is correct.

As this is my first post please forgive any mistake i did.
