redirect chain due to pointing to old URL

Hello,

I sent the following to Google CSE customer support:

When you test my site with pingdom you get the following two redirect
chains — can this be fixed?

Remove the following redirect chain if possible:
https://www.google.com/cse/cse.js?cx=(my search engine ID)
https://cse.google.com/cse/cse.js?cx=(my search engine ID)

Remove the following redirect chain if possible:
https://www.google.com/cse/style/look/minimalist.css
https://cse.google.com/cse/style/look/minimalist.css

Their answer is:

We have already migrated from https://www.google.com/cse/ to https://cse.google.com/cse/ since more than 1 year and it is recommended to use https://cse.google.com/cse/ instead of http://www.google.com/cse/ or https://www.google.com/cse/ in all your API requests. If you don’t do that , Google is automatically doing 302 redirect to this URL.

It seems in your website, you are using old GSS code specific to http://www.google.com/cse.. and due to this reason you are seeing the issue.

In order to resolve the issue, i would recommend you to take the updated code snippets specific to https://cse.google.com/cse from GSS control panel->Setup->Get Code page and implement in your site instead of using the old code.

Any suggestions?
Thanks!
