When I test the performance of my website via GTmetrix.com it says that there are 2 static components without a far-future expiration date. and listed below links.
So I have asked about this before in past question about GTmextrix .
So what I wants to know is that is it OK these
js files to be saved in my server and then cached them via
.htaccess and also if its OK could anyone please tell me for how many days I can cache these files.
