| Avoid unnecessary headers (unnecessaryHeaders) | There are 60 responses that sets both a max-age and expires header. There are 25 responses that sets a pragma no-cache header (that is a request header). There are 60 responses that sets a server header. | 0 |
| Description: Do not send headers that you don't need. We look for p3p, cache-control and max-age, pragma, server and x-frame-options headers. Have a look at Andrew Betts - Headers for Hackers talk as a guide https://www.youtube.com/watch?v=k92ZbrY815c or read https://www.fastly.com/blog/headers-we-dont-want. | ||
