Generate LoadError in Scheme Handler

[Ken Thomas]

I have implemented ISchemeHandler to handle my own scheme via HttpWebRequest.  Everything works fine.  Up until something goes wrong... :)

Say I get a WebException during HttpWebRequest.GetResponse().  As I process the exception, I'd like to trigger ChromiumWebBrowser.LoadError event so that my error processing can follow the same path as the rest of my requests that are handled by CefSharp.

How can I generate a LoadError event when doing my own request processing?  Is there something I can set on the response object?

Is there a better solution for handling requests in my scheme handler and notifying the app that a network error occured?

I should have said I'm using CefSharp.WinForms v37.

Can't you just set the error response data from WebException and populate your response with that?

If it doesn't have a HTTP Status Code set (for other odd reasons) you can pick one of the HTTP failure codes to use instead. (i.e. 404, or whatever...)

I don't know whether or not that would cause a LoadError event though.

The underlying callback exposes a `Cancel` method that if called triggers an `Aborted` error.

It's not exposed in the current version though. It'll be there in the next major release (probably `43`)

For now, trying to set the StatusCode is probably the best bet.
