[AWS] How to avoid caching?

[Alejandro R. Mosteo Chagoyen]

Hello everybody.

I'm using AWS to build the GUI of my current project. However, I'm
noticing that the pages are cached in the browser.

Is there an easy mean to avoid caching? Some parameter in AWS that
enables anti-caching headers?

I could set these when I'm returning parsed templates in the source,
but other responses are textual and I would evade if possible the
hassle of providing the <head/> section of the page only to put these
anti-cache headers.

am I forgetting something? Has anyone faced this problem?
