caching dynamic images with Laravel Intervention library not working

Question

I am using Laravel 5 at the moment and taking advantage of the intervention image integration: http://image.intervention.io/

I am using it dynamically so images have a URL like this:

http://example.org/media/1600x340/2/image_name.jpg

So all working, but im noticing these images will not cache. Other do, but not my dynamic ones.

This is my htaccess

<FilesMatch "\.(ico|pdf|jpg|jpeg|png|gif|html|htm|xml|txt|xsl)$">
    Header set Cache-Control "max-age=31536050"
</FilesMatch>

<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpg "access plus 1 year"
ExpiresByType image/jpeg "access plus 1 year"
ExpiresByType image/gif "access plus 1 year"
ExpiresByType image/png "access plus 1 year"
ExpiresByType text/css "access plus 1 month"
ExpiresByType application/pdf "access plus 1 month"
ExpiresByType text/x-javascript "access plus 1 month"
ExpiresByType application/x-shockwave-flash "access plus 1 month"
ExpiresByType image/x-icon "access plus 1 year"
ExpiresDefault "access plus 2 days"
</IfModule>

If I actually connect via FTP and look at the cached images, they are stored like this:

/storage/framework/cache/55/ba/0245f7453543100cf0aaa4709eca82f4

What is the point in caching if it has to reload it every time? I suspect the problem is that the browser doesn't know what these files are (they have no extension) so it doesn't cache them.

Here is some example laravel code:

$cache_image = Image::cache( function ( $image ) use ( $size, $name ) {
    return $image->make( url( '/uploads/' . $name ) )->resize( $size[0], $size[1], function ( $constraint ) {
        $constraint->aspectRatio();
        $constraint->upsize();
    } );
}, $cache_length )->sharpen(5);

...

return Response::make( $cache_image, 200, [ 'Content-Type' => 'image' ] );

Header in chrome looks like this:

Any ideas? Hopefully I can sort this out with the htaccess file

Answer 1

you can cache it at browser side. simply add header to response as below,

return Response::make( $cache_image, 200, [ 'Content-Type' => 'image' ] )
       ->setMaxAge(604800) //seconds
       ->setPublic();
