The Tracing HTTP Correlation Header Protocol specifies the E2EActivity HTTP header.
In HTTP/1.1, an HTTP client can specify a unique identifier for an HTTP message by including the E2EActivity HTTP header in the HTTP message. When the message is received by the HTTP server, the identifier can be used when emitting traces to provide a correlation between generated traces and incoming messages from the client.<1>
There are no changes to the HTTP messages sent from the server to the client based on receipt of the E2EActivity HTTP header.
