Parameters:

connection - the URLConnection of the HTTP request to be tagged and timed

Returns:

a WebRequestTracer which allows adding timing information

traceWebRequest

public WebRequestTracer traceWebRequest(java.lang.String url)

Description copied from interface: Session

Allows tracing and timing of a web request handled by any 3rd party HTTP Client (e.g. Apache, Google, Jetty, ...). In this case the Dynatrace HTTP header (OpenKitConstants.WEBREQUEST_TAG_HEADER) has to be set manually to the tag value of this WebRequestTracer.
If the web request is continued on a server-side Agent (e.g. Java, .NET, ...) this Session will be correlated to the resulting server-side PurePath.
