Does App.HTMLHeader Load for Each Page?

Does App.HTMLHeader Load for every WebPage (e.g. WebPage.Show) or only when the main page loads?
Trying to figure how I can define a Header and Footer once and use on every WebPage.


App.HTMLHeader loads once, when the initial page and framework are delivered to the browser. Every page after that is delivered without a page reload.

Thank you!

Quick followup. Any way to create a common header with an image across all of my WebPages without duplicating the code on each page? i.e. like a re-usable component.

Use a WebContainer.

Perfect. Thanks
