Hello yuhuisg, it seems that it is not possible to "force" AA hit as POST request. "AppMeasurement doesn't have an option to manually force a POST call. It will, however, automatically generate a POST call if the request size is greater than 2047 bytes."

Hello, I would like to know if Adobe has any limit on the length of product string in Adobe Launch. I try to implement product impression in Adobe Launch, and notice that if there are too many products (s.products is more than 100KB) the rule fires but no beacon was sent.  

It seems that the clearVars was fixed within the latest release: https://docs.adobelaunch.com/extension-reference/web/adobe-analytics-extension/adobe-analytics-release-notes Have anyone been successful with it? We still have troubles clearing the variables though.
