how to use Specify a cache validator the bmz_cache iamges and js,css in template

[gunni]

I just saw now that the original .htaccess inside "includes" directory allready has the ExpiresByType
so only need to change the time you could accept for cache of your css / js files.
A3600 means 3600 seconds which is 1 hour.
The CSS file expiration is not suggested to be 1 month as sample above and depends when you
change it but making it too long could damage your site so be careful...
I put my css to be 1 week.

Thank you, but I don't have with problem of the css / js files expiry. only the first 4 files in my post had file expiry issues, the 2nd list had issues with not having a cookie-free domain... which as I mentioned other here seemed to have solved, without hosting the pictures on another domain.

The warning for those 4 files is:

The following resources are missing a cache validator. Resources that do not specify a cache validator cannot be refreshed efficiently. Specify a Last-Modified or ETag header to enable cache validation for the following resources:

Adding that code in the .htacess of the same folder does not fix it.

This is the warning I seem to be unable to fix:

The following resources are missing a cache validator. Resources that do not specify a cache validator cannot be refreshed efficiently. Specify a Last-Modified or ETag header to enable cache validation for the following resources:

They are in the /includes/templates/responsive_sheffield_blue/images folder.

This is the warning I seem to be unable to fix:


They are in the /includes/templates/responsive_sheffield_blue/images folder.

Sounds strange...
My template images which are located at the same folder as yours, are not showing this warning message.
I have htaccess file in /includes folder. No htaccess under that directory.
Check if you have the same.

I have this .htacess file in the /include folder:

I have no other .htacess files within that folder structure.

@ttfan, try to delete the .htacess in /includes/templates/responsive_sheffield_blue/images/ folder
And use this .htacess file in /includes/ folder:

Thank you gunni, but unfortunately it made no difference...bizarre!!!

You can see the report here:

Any update on this subject. I have this:

The following resources are missing a cache validator. Resources that do not specify a cache validator cannot be refreshed efficiently. Specify a Last-Modified or ETag header to enable cache validation for the following resources:
