How to cache iframe in django

Question

I am building a django app and one of my templates has a mapstore iframe on it. That iframe is kind of heavy. Is there any way to cahce that iframe, or all the template, i dont have to wait so long every time the page is loaded. this is the iframe

<iframe
    src="http://tedcap.denebinc.com/mapstore/#/viewer/openlayers/1"
    frameborder="0"
    width="100%"
    height="400"
    allowtransparency
></iframe>
