Michael Neale - CORS: Cross-domain requests with JavaScript
You all know the same origin policy. And you have all probably heard about json-p. But there is a better way: CORS. With oauth, openid, and applications opening up JSON-based endpoints, your browser is the perfect place to combine data into new apps - less server side programming needed. CORS allows you to have your web apps talk directly and securely to any server, not just the origin. It is relatively simple to use, with a few tricks and gotchas. Let me show you how it works and how it can be setup (warning: some servers will be hurt).

Cross Site HTTP Requests
Cross-site HTTP requests are HTTP requests at URL addresses other than the domain of the resource making the request. The CORS specification allows the server side (that returns the resource we try to retrieve using the XHR object) to serve the resource to requests coming from resources that were served from other domains.

Fixed CORS problems and No Access-Control-Allow-Origin header errors with Ionic. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8100' is therefore not allowed access. Add these 3 line code in your header. header('Access-Control-Allow-Origin: *'); header('Access-Control-Allow-Methods: GET, POST'); header("Access-Control-Allow-Headers: X-Requested-With");

Getting a 'Cross-Origin Request Blocked' error? This video shows you how to quickly prevent these errors from occurring when sending web requests in Angular. The errors are typically formatted like this: Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://localhost:3000/. (Reason: CORS header 'Access-Control-Allow-Origin' missing). It can be fixed by adding some code to your webserver/API that adds the 'Access-Control-Allow-Headers' and 'Access-Control-Allow-Origin' headers to the response.

HTTP Protocol with method | PUT, GET, DELETE, POST, HEAD, OPTIONS, TRACE | Part -1
Follow me on FaceBook: https://www.facebook.com/TechTalkDebu Instagram: next_d_paul and LinkedIn : https://www.linkedin.com/in/debu-paul-2817a5121/ if you like my video, please subscribe to my channel and share the video The Hypertext Transfer Protocol (HTTP) is an application-level protocol for distributed, collaborative, hypermedia information systems. There are three basic features that make HTTP a simple but powerful protocol: HTTP is connectionless , HTTP is media independent , HTTP is stateless The HTTP protocol is a request/response protocol based on the client/server based architecture where web browsers, robots and search engines, etc. act like HTTP clients, and the Web server acts as a server. By Default request method of the http protocol is GET. whenever we visit any websites we call with GET method. HTTP Method : GET - The GET method is used to retrieve information from the given server using a given URI. Requests using GET should only retrieve data and should have no other effect on the data. POST - A POST request is used to send data to the server, for example, customer information, file upload, etc. using HTML forms. PUT - Replaces all the current representations of the target resource with the uploaded content. DELETE - Removes all the current representations of the target resource given by URI. CONNECT - Establishes a tunnel to the server identified by a given URI. OPTIONS - Describe the communication options for the target resource. TRACE - Performs a message loop back test along with the path to the target resource. HEAD - Same as GET, but it transfers the status line and the header section only. HTTP OPTIONS introduce in HTTP 1.1 ( earlier HTTP version was HTTP 1.0 ) Sample Server side Code : @OPTIONS @Produces(MediaType.APPLICATION_JSON) @Path("/") public Response optionsForBookResource() { return Response.status(200) .header("Allow","POST, PUT, GET") .header("Content-Type", MediaType.APPLICATION_JSON) .header("Content-Length", "0") .build(); } Thanks & Regards, Debu Paul

Cross-Origin Resource Sharing (CORS)
Alex Corn discusses how cross-origin resource sharing (CORS) works to resolve network problems caused by same-origin policy, and how it should be configured. Same-origin policy is a feature of modern web browsers that restricts scripts hosted on one website from making calls to another website. While useful from a security perspective, this policy can restrict certain legitimate use cases in which there is no security threat. The best solution to allow those legitimate cases to function properly is to employ CORS. This Cyber Minute discusses how CORS works and how it should be configured to avoid risk.
