Hi @jkpanera!
As already mentioned by some other members of this community, I would suggest to perform some root cause analysis on the issue that you are outlining. Some questions that should be answered before pointing to the AEM product source code would be:
- What instance is causing the redirect? AEM author instance? AEM publish instance?
- Could the redirect be caused by the webserver and/or dispatcher? Have you tried requesting the asset directly from the AEM instance, no dispatcher involved?
- Is the issue reproducible a.) on other environments and/or b.) on a plain vanilla instance?
- Have you tried deactivating some potential candidates that could cause the redirect to identify the actual root?
- Have you checked resource resolution and mappings (in the OSGI web console) to see how the request is resolved?
- You may also want to check the "Recent requests" view to get an insight into the applied filter chain as this is something that you specifically mention as something that you are looking for.
However, from my experience and without further knowledge about your setup or what you have already checked, I would most likely suspect this to be a dispatcher issue or somehow related to URL manipulation. You may want to check this article for potential candidates that could lead to the described behavior.
Once you have gained some more insights about the root cause, you may find a resolution somewhere in your specific setup (code, configuration, etc.). If you have indications that this might be a product issue, feel free to create a support ticket for our customer care team.
While I understand your desire to debug through closed-source AEM product code to a certain degree, this is usually not necessary (and often barely helpful) for this kind of analysis. You won't be able to patch anything for internal code. Even if you try or do so, you will loose support. For a proper analysis, there are plenty of tools available (within AEM and the stack as well as general Java analysis tools). From my personal experience, debugging through product internal source code is only helpful in rare edge cases.
If you still feel that AEM should be completely open-sourced, you may post this as a kind of feature request on this community (I'm not judging about chances of success here).
Hope that helps!
