Calling DB only once on page load

Question

I am developing an angular app, I have a Stored Proc using in which i have a lot of data related to multiple pages. I want to call that SP in master page only and I will save data in multiple variables related to diff-diff pages.

On master page i want to display some of the data and further u have some links in master page which will navigate to respective pages. On those respective pages i don't want to call separate SP, i want to utilize data which i already got on master page.

I need help to find out proper approach for this.
