Cookie sharing between different ports

Question

I have application 1 (C #) hosted on port: 80 and application 2 (nodejs) hosted on port: 3030. Both are on the local host.

The request workflow is as follows:

• The browser sends a request to the application 1
• application 1 sends back the number of cookies
• later the browser sends a request to application 2
• ^ The problem is at the last step, the cookie is not included in the request.

Things I tried / understood:

• I understand that this is a restriction on policies of the same origin, and because of different ports # the browser considers them as different domains.

• In Appendix 1 (using System.Web.HttpCookie) I tried to set a specific port for the domain ("127.0.0.1:3030"), but it looks like the browser is not accepting it or ignoring it.

  //c# code
  var testCookie1 = new HttpCookie("Test", "testValue");
  testCookie1.Domain = "127.0.0.1:3030";
  testCookie1.Path = "/";
  testCookie1.Expires = DateTime.Now.AddDays(1);
  Response.SetCookie(testCookie1);
  
  var testCookie2 = new HttpCookie("Test2", "testValue2");
  testCookie2.Domain = "127.0.0.1";
  testCookie2.Path = "/";
  testCookie2.Expires = DateTime.Now.AddDays(1);
  Response.SetCookie(testCookie2);
  

The server sends back a cookie with the port number attached to it, but the browser seems to ignore it.

and here are my ajax calls:

   var request = $.ajax({
        url: 'http://127.0.0.1:3030/SomeTask',
        type: 'POST',
        crossDomain: true,
    });

Answer 1

In this case, your domain will be the same as localhost, so there should be no problems.

Another thing: the port is part of the URI, not the domain, the domain is also part of the URI, so you mix apples and fruits ...
