Page load timing (sometimes referred to as real user monitoring or RUM) creates the following cookies for session tracking in end-user browsers. Cookies can be monitored and deleted from your browser. Since browsers create and store cookies, they are also the most direct way to access, manage, and delete cookies.
This cookie is only created in browsers that do not support the Navigation Timing API. When a browser supports the Navigation Timing API, a native interface can be used to determine navigation start time.
Firefox versions 7 or higher support the Navigation Timing API. However, a bug exists in Firefox's early implementations of the Navigation Timing API that New Relic Browser works around by using this cookie.
|Navigation start time||Navigation start time is required to measure end user response time. The cookie is written when the current page unloads (as the next navigation begins).|
|Document location||Stored as a hash. The document location is used with the referring page URL to validate that the start time refers to the page that was previously being viewed or refreshed (to avoid using an invalid start time from a different navigation).|
|Referring page URLs||Stored as a hash. The referring page URL is used with the document location to validate that the start time refers to the page that was previously being viewed or refreshed (to avoid using an invalid start time from a different navigation).|
|Domain||The NREUM cookie is associated with the root path of the domain in which the New Relic agent executes.|
|Expiration||NREUM is a session cookie that is deleted when the browser closes.|
This cookie is created only when a token is handed out to an end user by the New Relic collector.
This cookie is used to communicate between the New Relic collector aggregating end user metrics and the agent(s) running in the associated web application. A token identifies and correlates application tier transaction traces with corresponding browser traces.
|Token identifier||The 16-character token identifier helps with cross-domain communication between the New Relic collector and the New Relic agent.|
|Domain||The NRAGENT cookie is associated with the root path of the domain in which the New Relic agent executes.|
|Expiration||NRAGENT is a session cookie that is deleted when the browser closes.|
The JSESSIONID cookie is used to store a session identifier so that New Relic can monitor session counts for an application. The cookie value is generated by Jetty.
|Session identifier||This is used by New Relic to monitor session counts for an application.|
|Domain||The JSESSIONID cookie is associated with the New Relic domain.|
|Expiration||JSESSIONID is a session cookie that is deleted when the browser closes.|
