This functions on some browsers since they’re dumb sufficient to just accept the mime style within the server rather than study it within the file or some similar mix. Even better When you are hand creating your own personal code Then you really don’t require to hide it through the anti-virus because the anti-virus hasn't heard of it and doesn’t know what it is.
