When it is not possible to modify the HTTP headers on the server side, it is possible to specify them directly in the body of the page using the META HTTP-Equiv . The content of the tag is compiled according to the rules for HTTP headers with the only difference being that the value of the http-equiv attribute is added to the title of the header (the left part before the rotation), and its value to the value of the content attribute. More information about HTTP headers can be found on the Mozilla Developer Network in the HTTP Headerssection.
