http-headers

问题 Net 4 and C#. I would need set send to Browser Cache-Control ( Cache-Control: no-cache ) in the HTTP Response header for a Web Form page. Any idea how to do it?

See this answer for more accurate solution: Making sure a web page is not cached, across all browsers 回答2: In MVC you can set it in the

问题 My backend requires the 'Content-Type' request header to be exactly 'application/json'. This is a CORS request and everything works fine in Chrome. The exact header, from developer tools network tab source: Content-Type: application/json I set this in AngularJS with $http.default.headers.post and it works fine in Chrome. However it doesn't work in Firefox. Firefox sends this instead: Content-Type: application/json; charset=UTF-8 I tried to change headers by: settings $http.default.headers

问题 How can I set HTTP headers in my Firefox extension? I'll make it so these are only sent while hitting my site so I can detect if the plugin is installed or not and not promote the plugin if it is. 回答1: Here's the most compact way I found to make this work: Components.classes["@mozilla.org/observer-service;1"].getService(Components.interfaces.nsIObserverService ).addObserver({ observe : function(subject, topic, data) { var channel = subject.QueryInterface( Components.interfaces.nsIHttpChannel

问题 Hello I am trying to do a http request with Basic Auth, but I can't set the header authorization and it is allowed in server. Ajax : $.ajax({ xhrFields: { withCredentials: true }, beforeSend: function(xhr){xhr.setRequestHeader('authorization', 'Basic cmFmmFuQHBoaWlubm92YXRpb25zLmNv=');}, url : 'http://www.vozi.dev.br/api/audio', type: 'POST', data: JSON.stringify(sender), dataType: 'json', contentType: 'application/json', success : function(data, textStatus, jqXHR) { //do something } }); Http

问题 In the current HTTP spec, the URL fragment (the part of the URL including and following the # ) is not sent to the server in any way. However with the increased spread of AJAX, which uses the fragment to maintain some form of state, there are a lot of situations where it would be useful for the server to have knowledge of the URL fragment at request time. For example, if you go to http://facebook.com, then click a user name in your stream, the URL will become http://faceboook.com/#!/username

问题 We use custom headers to authenticate our web apps. An http proxy service intercepts requests, confirms the authenticity of the user and then injects custom headers into the request. In order to test the app, I need to write those headers into the request before it hits my ApplicationController methods. Right now, the current hack works for all my non-javascript tests: # in hooks.rb Before do require 'capybara/driver/rack_test_driver' module Capybara::Driver class Authentic < RackTest def env
