Hello , I am having issues with cache control header for HEAD request, Apache is getting content from AEM using a dispatcher module. When the content is not cached on Apache2.2 ,using curl -I is displaying cache control header but on 2.4 it is missing cache header.
➤ curl -I https://local/support.html -k HTTP/1.1 200 OK Date: Wed, 18 Nov 2020 22:57:15 GMT Server: Apache Strict-Transport-Security: max-age=31536000; includeSubDomains X-Frame-Options: SAMEORIGIN Content-Security-Policy: frame-ancestors 'self' X-Content-Type-Options: nosniff X-XSS-Protection: 1; mode=block Content-Type: text/html;charset=utf-8 Content-Language: en If a request is get cache control header appears . curl -i https://localhost/support.html -k |more % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 0 201k 0 740 0 0 1831 0 0:01:52 --:--:-- 0:01:52 1827HTTP/1.1 200 OK Date: Wed, 18 Nov 2020 23:11:58 GMT Server: Apache Strict-Transport-Security: max-age=31536000; includeSubDomains X-Frame-Options: SAMEORIGIN Content-Security-Policy: frame-ancestors 'self' Last-Modified: Wed, 18 Nov 2020 23:11:50 GMT Accept-Ranges: bytes Content-Length: 206003 Expires: Thu, 19 Nov 2020 23:11:58 GMT Vary: Accept-Encoding X-XSS-Protection: 1; mode=block X-Content-Type-Options: nosniff Cache-Control: public, max-age=86400 Content-Type: text/html Content-Language: en want to know if Apache ignores the cache header for HEAD request on 2,4 and only applies cache header for GET request.
