performance - JavaScript: Is it is possible to preload external sites? -


I could not find an answer to this special question on stack overflow. Not particularly looking for an implementation (unless it already does not exist), but ...

I have an intranet app that loads very quickly, with many external sites There are links to, all of which we can assume to load slowly, the user will definitely not do this by going to all the links on the page (we do not but it is unlikely that They are the first ten seconds Itr loading open a linked page).

Before clicking on a link, would you like to start downloading these external links without opening a new window / tab? I've noticed that there is such a capability, but especially against external sites (or, sites with different CSS / JS files) are warned against loading

Anyhoo, what with JS Is it possible to start an external site caching (or anything else for that matter)? Would it be possible, say, to load the HTML page first but not to fix any associated CSS / JS files. Click OK. Even if it is an one element of an external site, which can be downloaded in the past, it would be a useful advantage ...

  
div style = "display: none;" & gt; "itemprop =" text "> < P> & lt; Iframe name = "i2" src = "www.xyz.com" & gt; & Lt; / Iframe & gt; & Lt; Iframe name = "i3" src = "www.xyzsf.com" & gt; & Lt; / Iframe & gt; & Lt; Iframe name = "i1" src = "www.xysfz.com" & gt; & Lt; / Iframe & gt; ... & lt; / Div & gt;
