Hello, we use 204 response (by adding send_image=0 in request)
But in chrome we see that when browser gets 204 response - it is generate some additional identical requests to piwik (about 4). So we added send_image=1 and now only one request goes to piwik.
This post was flagged by the community and is temporarily hidden.
The question is, why in the preparation of 204 - th code, the browser sends repeated requests and how to fix it ?
