Stream

By default, Fiddler Everywhere uses buffering mode, which means that the responses are fully collected before any part is sent to the client. Buffering alters the responses (for example, an image won't begin to download until the containing page download is complete). With streaming mode, the server's responses are immediately returned to the client as it is downloaded. In streaming mode, tampering with the response body is not possible.

  1. Click on the Stream button to enable/disable the streaming mode. Stream Toggle button

Streaming mode is useful for low-level network timing scenarios (for example, by design some browsers will parse partially-downloaded HTML, and that would start downloading external resources in parallel before the remote server has finished delivering the content).

Streaming mode is also useful in cases where a site delivers audo or video streams. These kind of never-ending streams can't be buffered by Fiddler Everywhere.
