Hi @Sylvain_Juge the AEM service is using Apache sling framework so I believe it is using Apache Http client for forwarding the request, we don't have access to the code as its owned by other team. But we will try to get the info.
There is another thread - APM Java agent startup error with Adobe Experience Manager - #4 by felixbarny where it was asked that whether elastic-apm automatically shows the forwards made by AEM application . I am not sure whether that feature is implemented or not.
Any help is much appreciated.
