Firstly, the relevant HTTP spec is RFC 7234. If you look at the spec you will observe two things: The spec never requires, under any circumstances, that a cache serves a cached version of content without revalidating. There are plenty of places where the spec notes that a cache MUST NOT use cached content to … Read more
The frame-src CSP directive (which is deprecated and replaced by child-src) determines what sources can be used in a frame on a page. The X-Frame-Options response header, on the other hand, determines what other pages can use that page in an iframe. In your case, http://a.com with X-Frame-Options: DENY indicates that no other page can … Read more

Authorization is the primary header used by clients to authenticate against peers in HTTP as foreseen in RFC 7235. It is often linked to the Basic authentication scheme as per RFC 7617, but that is not a given.

Your error InvalidStateError: An attempt was made to use an object that is not, or is no longer, usable appears because you must call setRequestHeader after calling open. Simply move your setRequestHeader line below your open line (but before send): xmlhttp.open(“POST”, url); xmlhttp.setRequestHeader(“x-filename”, photoId); xmlhttp.send(formData);
Simply call getUrl() on URLConnection instance after calling getInputStream(): URLConnection con = new URL( url ).openConnection(); System.out.println( “orignal url: ” + con.getURL() ); con.connect(); System.out.println( “connected url: ” + con.getURL() ); InputStream is = con.getInputStream(); System.out.println( “redirected url: ” + con.getURL() ); is.close(); If you need to know whether the redirection happened before actually getting … Read more

To access the user-agent, use navigator.userAgent. As others have indicated, the HTTP headers are not available, but you specifically asked about the referer and user-agent, which are available … Read more
