Intermittently getting 416 errors with Azure CDN

[rahulbpatel]

We are intermittently getting HTTP 416 errors on v1.1.0 storage provider when fronted by Azure CDN from Microsoft. After adding additional logging we suspect it is due to large file chunking where the CDN requests 8MB chunks:

In the request headers

Range:bytes=0-8388607

In the response header:

Content-Range:bytes */495942

Looking at the source code this looks like this is expected if the Range is larger than the content size.

It seems like this check is unnecessary and if the Range bytes are larger than the content size it should return up to the content size?

@rahulbpatel Thanks for reporting this and apologies for the very late reply. Version 1.x targets Umbraco 9, which has been EOL since December 2022 and we've completely removed the custom middleware in #36, so I recommend updating to Umbraco 10 and Storage Providers 10.

I'll close this issue, as I don't expect the ASP.NET Core StaticFileMiddleware will have the same issue (but feel free to re-open if you do).
