I get %89 score on my page http://www.ghlsports.com/, in the Expires Headers section with this comment
There is 1 static component without a far-future expiration date.
http://www.google-analytics.com/ga.js
Is their a method to fix this, I found this article
Is this a good idea / bad idea any other recommendations
Don’t do it. Google Analytics is used across so much of the web that it is almost guaranteed to be in a user’s cache even with a short expires.
If you want to get a perfect score, than put it on your server and have it cached for as long as you want.
Create a cron job to always download the latest version from google 
Like Patrick said,
Don’t do it.
Our website get %84 score on my page http://www.pajasaapartments.com/ in google page speed and showing following error
http://www.google-analytics.com/ga.js missing expiry time
Suggest how to remove same .
Don’t worry about it, it’s not in your control. As long as you are using the async analytics snippet you are fine. Optimize of the actual performance, not necessarily the scores.
i checked my website www.ace-services.uk in Gtmetrix and shows Add Expires headers https://www.google-analytics.com/analytics.js Grade C and need to optimise , shall i leave that as it is ?
