Loading images without extension

[Thijs]

Hi!

I'm having some issues when loading images from a CDN, where the resources are available from a url without extension. For example:
https://vg-images.condecdn.net/image/rymMV59dRxN/crop/200/square

You'll see a lot of this when opening http://www.vogue.co.uk

The server does respond with a proper MIME-type: image/jpeg. So I'd expect the browser to just load and treat it as an image.

However when using CEF, the resource gets the status CANCELED and is never fully loaded.

For a normal asset I get these function calls from CefRequestHandler:

Code: Select all

OnBeforeResourceLoad()
GetResourceResponseFilter()
OnResourceResponse()
OnResourceLoadComplete() // URLRequestStatus = UR_SUCCESS


However for the extension-less images I only get these function calls:

Code: Select all

OnBeforeResourceLoad()
OnResourceLoadComplete() // URLRequestStatus = UR_CANCELED, response->GetMimeType() = NULL


Is this expected behaviour? Is there anything I can do to force the image to load?
I've tried adding request headers like:
Accept: */*
Cache-Control: no-cache
Pragma: no-cache

What OS and CEF version? How does it behave in Google Chrome at the same version?

[Thijs]

OS: Windows 10 x64
CEF: 3.2785.1482.g16e49fb

I noticed that in the latest cefclient build the images were loading properly. Since it was easier for me to update my application to the latest CEF than to downgrade Chrome, I did the former.

Now it all works good! Using CEF 3.2924.1566.ga6a3da2.

Thanks for the quick response though, and I'll make sure to check the latest CEF version and compare to Chrome from now on
