You are right, the link which you posted in the comment would be probably the best approach. As your question sounded interesting i tried it out.

Applications SHOULD use this field to indicate the transfer-length of the message-body, unless this is prohibited by the rules in section 4.4.

In Express >= 3.0.0rc5: app.disable(‘x-powered-by’); Here is a simple middleware that removes the header in earlier versions of Express: app.use(function (req, res, next) { res.removeHeader(“x-powered-by”); next(); });
Sure, use a Content-disposition header header(‘Content-Disposition: attachment; filename=”filetodownload.jpg”‘); if you wish to provide a default filename, but not automatic download, this seems to work. header(‘Content-Disposition: filename=”filetodownload.jpg”‘);
if (Request.Headers[“XYZComponent”].Count() > 0) … will attempted to count the number of characters in the returned string, but if the header doesn’t exist it will return NULL, hence why it’s throwing an exception. Your second example effectively does the same thing, it will search through the collection of Headers and return NULL if it doesn’t … Read more
The JavaScript MIME Type When sending JavaScript content, you should use text/javascript as per RFC 9239. Aliases application/javascript, application/x-javascript, text/javascript1.0, text/javascript1.1, text/javascript1.2, text/javascript1.3, text/javascript1.4, text/javascript1.5, text/jscript, and text/livescript are deprecated aliases for it. If you are writing a tool which consumes JavaScript (e.g. an HTTP client) then you should consider supporting them for backwards compatibility. … Read more
