  • Firefox Agent

I created filters to see specific traffic in my test results, but I see OCSP traffic from the Firefox agent. How do I exclude OCSP traffic?


URLs for OCSP are only seen in Firefox playback in the Dynatrace Recorder. They are not filtered during playback. This is an expected behavior related to native Firefox support for OCSP.

Internet Explorer supports OCSP in the Windows operating system, so these URLs do not appear in the IE playback agent.

To disable OCSP support in the Firefox Agent at runtime, add a Custom action with the following code.

Set the target window to control.

var prefs = Components.classes[";1"].getService(Components.interfaces.nsIPrefBranch);
prefs.setIntPref("security.OCSP.enabled", 0);

    I want to comment 


    here, so it is searchable later using this reference.

    This is broader to search and can be used for other references then just OCSP calls.
