What does rb mean?


Hi Everyone,

A security software is detecting some Cross-Site Scripting and Illegal Resources Access event of the following events (Screenshots are attached)...

I need to know what does "rb_bjd443882" mean on the url?

I figured out that bjd443882  comes from  our Dynatrace environment, but I'm not sure what does the letters rb mean. 

Thanks in advance

The requests are from the Dynatrace RUM functionality.

Interesting question! I would imagine that r stands for "Ruxit" or "Real user monitoring". Don't really know, and believe it's not that important.

More information on how this works can be seen in this link:

IIRC it's request beacon, but I might have just made that up for myself at one point 😄  Might also be ruxit/rum beacon. 

In any case, this is the monitoring data captured from the RUM script that is sent to the server async.
