1: 对比mod_expires 和mod_headers

?

You probably just want to use mod_expires, as this allow for sending of both Cache-Control header and Expires headers automatically and can allow you to specify by both access time and file modification time. It also allows you to set different defaults by file type.

Using mod_expires you could set the default expiry using the following directive:

ExpiresDefault "access plus 2 days"

Of course mod_headers is a much more general module that allows you to do some of the same stuff, but generally used more for creating custom headers or manage multiple (possibly conflicting) headers.

  # Manifest files

    # If you are providing a web application manifest file (see the
    # specification: http://w3c.github.io/manifest/), it is recommended
    # that you serve it with the `application/manifest+json` media type.
    #
    # Because the web application manifest file doesn't have its own
    # unique file extension, you can set its media type either by matching:
    #
    # 1) the exact location of the file (this can be done using a directive
    #    such as `<Location>`, but it will NOT work in the `.htaccess` file,
    #    so you will have to do it in the main server configuration file or
    #    inside of a `<VirtualHost>` container)
    #
    #    e.g.:
    #
    #       <Location "/.well-known/manifest.json">
    #           AddType application/manifest+json               json
    #       </Location>
    #
    # 2) the filename (this can be problematic as you will need to ensure
    #    that you don't have any other file with the same name as the one
    #    you gave to your web application manifest file)
    #
    #    e.g.:
    #
    #       <Files "manifest.json">
    #           AddType application/manifest+json               json
