When I test the performance of my website through GTmetrix.com, it says there are 2 static components without a future expiration date. and the links are listed below.
So I asked about this before in a previous question about GTmextrix.
So what I want to know is that ok these
js files to save on my server and then cache them through
.htaccess And also, if it's ok, could someone tell me how many days I can cache these files?
