If i want Each browser is different Chromium object use CustomeScheme Object,some Unexpected question

[PingXD]

Each browser custom protocol is the same, but use different IResourceSchemeHandlerFactory copy
The implementation is as follows:

     var setting = new RequestContextSettings();

        RequestContext req = new RequestContext(setting);
        var scheme = new HttpBridgeSchemeHandle(chromiumWebBrowser, this);  //this object use ISchemeHandlerFactory interface
        req.RegisterSchemeHandlerFactory("https", "bridge.com", scheme);
        chromiumWebBrowser.RequestContext = req;

I use the same custom protocol for each browser instance,But the constructor is the browser object currently created
That is, each browser object has its own SchemeHandlerFactory
However, each time a new browser object is created, the existing browser object ISchemeHandlerFactory scheme will be replaced by a new one
It's like creating A browser A with A1 SchemeHandlerFactory and then creating A browser B with B1 SchemeHandlerFactory where browser A would want to use A1Factory but now browser A is using B1Factory

What's your question exactly?

[PingXD]

Each old ISchemeHandlerFactory scheme will be replaced by a new one
Creating A browser as A use A1 SchemeHandlerFactory and then creating browser B with B1 SchemeHandlerFactory where browser A would want to use A1Factory but now browser A is using B1Factory
Question:
How do I isolate each browser's SchemeHandlerFactory from each other

How do I isolate each browser's SchemeHandlerFactory from each other

They are tied to a RequestContext. A RequestContext van be shared by one or more ChromiumWebBrowser instances.

Still not quite sure I understand what you are asking.

ok,The problem has been solved
now has a new problem: I use RequestContext to register SchemeHandler how allow CROS, my custome scheme is 'xbro', It is not a standard protocol
RequestContextSettings rcs = new RequestContextSettings(); rcs.CachePath = Program.TempPath(); RequestContext req = new RequestContext(rcs, new RequestContextHandle(this, chromiumWebBrowser)); req.RegisterSchemeHandlerFactory("xbro", null, new ResourceSchemeHandlerFactory()); chromiumWebBrowser.RequestContext = req;

Making CORS requests to a custom scheme is not currently supported.

• Use https scheme and specify a domain when registering scheme handler factory.
• intercept arbitrary requests using http://cefsharp.github.io/api/96.0.x/html/M_CefSharp_IRequestContextHandler_GetResourceRequestHandler.htm
