Please suggest me how can i add expiry for online scripts Thanks
As of my findings on your question, It is NOT POSSIBLE and it is not recommended also. Go through this How can I add expire headers for scripts that are not on my server?
You cannot set expiry headers or any headers to files that are served from a third party. Your options are:
Copy those files locally and set your desired headers
Keep it as is and ignore any reports saying headers missing or whatever
Only in rare cases I see advantage in using #1. Otherwise, your best bet is to leave it alone.

There are many questions out there LIKE this PageSpeed Insights wrongly reporting cache policy But none address the issue of simply ignoring the cache policies that are stated by the .htaccess file. Normally I wouldn't worry so much about this, as our sites paint completely in under 2 seconds and user experience is great. But Management cares about pretty graphs and reports.
I have the following caching policies:
ExpiresActive On
# Images
ExpiresByType image/jpeg "access plus 1 year"
ExpiresByType image/gif "access plus 1 year"
ExpiresByType image/png "access plus 1 year"
ExpiresByType image/webp "access plus 1 year"
ExpiresByType image/svg+xml "access plus 1 year"
ExpiresByType image/x-icon "access plus 1 year"
# Video
ExpiresByType video/mp4 "access plus 1 year"
ExpiresByType video/mpeg "access plus 1 year"
ExpiresByType video/m4v "access plus 1 year"
# CSS, JavaScript
ExpiresByType text/css "access plus 1 week"
ExpiresByType text/javascript "access plus 1 month"
ExpiresByType application/javascript "access plus 1 month"
# Others
ExpiresByType application/pdf "access plus 1 month"
ExpiresByType application/x-shockwave-flash "access plus 1 month"
I want to point out one in particular since it makes it easy to point out the problem:
ExpiresByType video/m4v "access plus 1 year"
If you visit the site and view the headers for said file:
You can clearly see that the setting is being sent by header and is, thus, properly configured for a 1 year policy. HOWEVER .. When using Insights, OR Lighthouse individually they both report 30 days:
Not to mention all the other policies that are transferring properly in the header, but being completely ignored by LightHouse and Insights .. Does anyone have any answer for "why" this is happening? It's infuriating that even though the headers are obviously correctly sent, Lighthouse ignores them.
I have even tried something like this to no avail:
<filesMatch ".(ico|pdf|flv|jpg|jpeg|png|gif|js|css|swf|mp4|m4v|css|js)$">
Header set Cache-Control "max-age=31536000, public"
</filesMatch>
But I don't think that will make a difference, since the headers are, in fact, being sent correctly.
my website available in siteground hosting and i am updating image optimization as per suggestion Gtmetrix and add expire header but still not updating it showing up old
after i have also flush supercacher in hosting but still not updating
my expire header code like
############################################
## Add default Expires header

ExpiresActive On
ExpiresDefault "access plus 1 year"
ExpiresByType text/html A0

ExpiresByType video/mp4 "access plus 1 month"
ExpiresByType video/webm "access plus 1 month"

ExpiresByType application/xml "access plus 0 seconds"
ExpiresByType application/json "access plus 0 seconds"
ExpiresByType application/rss+xml "access plus 1 hour"
ExpiresByType application/atom+xml "access plus 1 hour"
</IfModule>
Any help would be appreciated.
Thanks.
My name is Georgi Ganchev and I am a Technical Support Supervisor at SiteGround.
I saw your thread and I decided to follow up.
The rules in your .htaccess are correct in general, but we recommend a longer expiration date set for your images, CSS and JS stored locally.
Please check the following article we have written about the most advised configuration:

In case the issue continues, please make sure you open a ticket through the User Area of your account with us and we will gladly help you out.

We were trying to get a wrong result. i was searching for a solution too but what i found after reading the test result with those lines code and without them:
this code is working but only with internal files.
this code will not work with external files(from other websites like google analytics js ...).
the test result will show you only the external files.
if you remove those lines of codes the result will be worst, and it will result in more files doesn't have an expired age.
I have an articles-blog and my articles may have a shelf-life of perhaps 1-2 weeks max. In my .htaccess I already have ExpiresByType rules (but the clutter in my MODx backend is still there and I do not understand the impact of these rules - code is below). I also have put my articles standard as indexable by the search engines.
When the shelf-life expires, I would like to permanently delete my articles. Now I do this manually and I have a whole lot of "red-crossed-out" articles titles in my back-end which makes me completely loose the overview.
My question is: What is MODx EVO best practise for my situation and is there an "automatic" way to permanently and completely (so no more red-crossed-out resource titles) remove expired articles from my MODx backend with pre-defined rules (for example, "if published time-period on the internet is 20 days then delete/remove article from MODx backend/database)"?

## Leverage Browser Caching ##
just got to know that setting expiry dates for static resources make your site go fast and jump in rankings.
My question is:
Does browser checks create date of the static resource?
If I make change to a css before 1 month, does server sends fresh copy and browser refreshes its cache?
This is the code I added to htaccess:
<IfModule mod_expires.c>
# Enable expirations
ExpiresActive On
# Default directive
ExpiresDefault "access plus 1 month"
# My favicon
ExpiresByType image/x-icon "access plus 1 year"
# Images
ExpiresByType image/gif "access plus 1 month"
ExpiresByType image/png "access plus 1 month"
ExpiresByType image/jpg "access plus 1 month"
ExpiresByType image/jpeg "access plus 1 month"
# CSS
ExpiresByType text/css "access plus 1 month"
# Javascript
ExpiresByType application/javascript "access plus 1 year"
</IfModule>
From mod_expires documentation:
The expiration date can set to be relative to either the time the source file was last modified, or to the time of the client access.
Here is the syntax:
ExpiresByType type/encoding "base[plus num type] [num type] ..."
where base is one of:
access
now (equivalent to 'access')
modification
The plus keyword is optional. num should be an integer value [acceptable to atoi()], and type is one of:
years
months
weeks
days
hours
minutes
seconds
So if you write:
ExpiresByType image/gif "access plus 1 month"
Your file will be cached as long as visitors keep requesting it without interruption for more than a month, even if you modify it.
You should then write instead:
ExpiresByType image/gif "modification plus 1 month"
Then your file will be cached for a month as long as it is not modified, otherwise the cache will be updated.
I have the following from http://web-sniffer.net/ :
Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0
I use Cloudflare and Custom Expired Rules for caching, but in the browser it seems that they are not caching.
Why is this happening?
Rules:
# Enable expirations
ExpiresActive On
# Default directive
ExpiresDefault "access plus 1 month"
# My favicon
ExpiresByType image/x-icon "access plus 1 year"
# Images
ExpiresByType image/gif "access plus 1 month"
ExpiresByType image/png "access plus 1 month"
ExpiresByType image/jpg "access plus 1 month"
ExpiresByType image/jpeg "access plus 1 month"
# CSS
ExpiresByType text/css "access 1 month"
# Javascript
ExpiresByType application/javascript "access plus 1 year"
</IfModule>
It would help if we knew the specific domain name here, also I would recommend opening a support ticket directly with CloudFlare. Our support team can then check your specific account settings, but for obvious privacy reasons can't discuss those here.
