RUM injection failure when Azure Front Door caching enabled

[GregOReilly]

We have found an issue when using kuberneres+OneAgent+RUM injection with some applications. Support helped us to eliminate possible causes and to narrow in on caching at the AFD level.

When caching is enabled, RUM injection does not work. If we disable caching on AFD, RUM Injection works every time.

To circumvent this issue, we've resorted to manual JavaScript injection.

Has anyone come across an alternative solution for this challenge?

Hi @GregOReilly, were you able to find an alternative solution for this issue? Thank you!

Hello Anna, manual injection was the only method that worked. Using Oneagent and automated injection of Javascript did not work with Cache enabled on Azure Front Door(s).

We have encountered this issue, we have temporarily disabled the cache in Azure Front Door.

Manual injection is not a viable solution as it defeats the main purpose of Dynatrace's RUM auto-injection feature.

Can the Dynatrace team prioritize this request, find a solution which supports RUM auto-injection? If necessary, Dynatrace should work with Microsoft to deliver the solution.

Thanks
