cross domain in cefsharp

Question

I used CefSharp for handling 2 scheme: "http" and "uc". At first I loaded page by http. After that, I called a "uc" link. It occurred the error "Cross origin requests are only supported for HTTP".

Until now, I can't find any solution. How to solve this problem?

There is a section of the chromium embedded guide on this subject: https://code.google.com/p/chromiumembedded/wiki/GeneralUsage#Request_Handling

You need to register your custom "uc" schema and set the "Standard" flag for CORS to work.

Alternatively, instead of using a custom scheme you can register a request handler for "http" and "customdomain" - and you will handle requests for http://customdomain/* and CORS will work just like with http.

For example:

var your_factory = XX;

var settings = new CefSettings();
settings.BrowserSubprocessPath = "CefSharp.BrowserSubprocess.exe";
settings.RegisterScheme(new CefCustomScheme {
    SchemeName = "http",
    SchemeHandlerFactory = your_factory,
    DomainName = "customdomain",
    IsStandard = true
});

Cef.Initialize(settings);
