etagΒΆ

The ETag of the feed, as specified in the HTTP headers.

The purpose of etag is explained more fully in ETag and Last-Modified Headers.

Tip

etag will only be present if the feed was retrieved from a web server, and only if the web server provided an ETag HTTP header for the feed. If the feed was parsed from a local file or from a string in memory, etag will not be present.
