What is the use of "https://dc.services.visualstudio.com/v2/track"

What is the use of "https://dc.services.visualstudio.com/v2/track" ? As it is used to track our application using Application Insights but in page refresh or page break it stop tracking after that.

It's an old question but (un)forturnately still relevant...

See: http://davidbanks.blog/Posts/redirectingApplicationInsights

It seems that the telemetry for Application Insights is currently (on the 11 May 2017) going to two endpoints:

• dc.services.visualstudio.com/v2/track is the endpoint for most of the metrics
• rt.services.visualstudio.com/v2/track seems to be exclusively for "Quick Pulse Service"
