Fiddler Ideas

Repro:

1. Save a JPEG on your desktop as foo.Jpg

2. Drag drop file to Fiddler

Observe:

- File does not have correct Content-Type response header.

File extensions should be treated as case-insensitive when mapping to MIME types (Utilities::ContentTypeForFileExtension).

3. Rename a text file to foo.map

4. Drag drop file to Fiddler

Observe:

- File does not have correct Content-Type response header from the registry.

It looks like the registry may not be getting consulted properly; perhaps this was done with the introduction of CustomMimeMappings.xml which was presumably added to better support running on Mono/Linux, but Fiddler should still fall back to the Windows registry on Windows.
