How to load markups in single page applications?

Question

Hi

I'm new to single page application development and i use ASP.NET MVC and KnockoutJS for this.

1. How to place HTML templates in separate files and call them whenever they are required?

2. I understood all of HTMLs loads and store(Cash) in memory, it decreases application performance at first loading.How to loads only those HTMLs that required for first application initial?

 

thanks
