[JS] TypeKit Local Caching

local.typekit.js

<!--

Questo codice si salva in localStorage le risorse interne di TypeKit
evitando il roundtrip di chiamata e il FOS.

Incollare lo snippet PRIMA del blocco :

<script src="https://use.typekit.net/gls5dvn.js"></script>
<script>try{Typekit.load({ async: true });}catch(e){}</script>

-->


<script>/* TypeKit */
!function(e,t,n,a,r,c,l,s,o){l=a[r],l&&(s=e.createElement("style"),
s.innerHTML=l,e.getElementsByTagName("head")[0].appendChild(s),
e.documentElement.className+=" wf-cached"),o=t[n],t[n]=function(e,p,u,i){
if("string"==typeof p&&p.indexOf(c)>-1){try{u=new XMLHttpRequest,
u.open("GET",p,!0),u.onreadystatechange=function(){try{4==u.readyState
&&(i=u.responseText.replace(/url\(\//g,"url("+c+"/"),i!==l&&(a[r]=i))}
catch(e){s&&(s.innerHTML="")}},u.send(null)}catch(d){}t[n]=o}return
o.apply(this,arguments)}}(document,Element.prototype,"setAttribute",
