Popup UI displays network requests from previous loads even after subsequent refresh events #809

Closed ghost closed 6 years ago

Describe the issue

Popup UI displays network requests from previous loads even after subsequent refresh events.

One or more specific URLs where the issue occurs

https://en.wikipedia.org/wiki/The_Good_Doctor_(TV_series)

Screenshot in which the issue can be seen

Steps for anyone to reproduce the issue

1) Keeping the uMatrix logger open, browse to https://en.wikipedia.org/wiki/The_Good_Doctor_(TV_series) and make sure all other tabs to this specific page are not open.

2) As this is the first load, all network requests fired for this event will be shown in the logger and in the Popup UI which are from domains wikimedia.org and wikipedia.org respectively.

3) Now hit refresh and keep an eye on the logger and as you can see only network requests from wikipedia.org will appear as all resources from wikimedia.org were already loaded and cached so the network request was never fired this time, hence it will not appear in the logger either.

4) Now open the Popup UI and you will still see *.wikimedia.org entry even though no network request was fired for this URL during the refresh event.

Expected result

Popup UI should only show a single entry from wikipedia.org on subsquent refresh events as resources from wikimedia.org are already loaded and cached, hence no network request was sent via Chrome.

Actual result

Popup UI still shows wikimedia.org entry even though no network requests was fired for this URL during the refresh event.

By design.

but the same behavior is not present in uBO's popup UI, why ?

I have created documentation for this: https://github.com/gorhill/uMatrix/wiki/Lingering-domain-entries-in-the-matrix.

Thank you, that does make sense for uMatrix's behavior.
