CEF1: Can I override http scheme with Scheme Handler?

[Czarek]

Hi there,

I'm not sure about that, I've read the comments in cef_scheme.h, but it's a bit
confusing. For example this sentence:

If |scheme_name| is a built-in scheme and no handler is returned by |factory|
then the built-in scheme handler factory will be called.

Why would I want to call CefRegisterSchemeHandlerFactory() with a factory that does
not return any handler?

There is probably a bug in the comment here:

If |scheme_name| is a custom scheme the CefRegisterCustomScheme() function
should be called for that scheme.

I couldn't find any function named "CefRegisterCustomScheme".

In this post [1] Marshall states that I can't override the file:// protocol, so this will also
be true for the http:// protocol?

Is my only option to use OnBeforeResourceLoad() to override the http:// protocol?

You can override HTTP protocol handling. Actually, now that I look at the code [1] it seems that you might be able to override the file handler as well (I haven't tested that, though, and I can't think of any advantages to doing so).

Thank you for clarifying.

You can also provide a custom resource handler in CefClient::GetResourceHandler.
I use this strategy to override the file:// protocol and it works well.
