92670 2012-07-30 13:18:45 -0700 Blank tab when loading many tabs from the same domain with EventSource 2012-07-30 15:37:11 -0700 1 1 1 Unclassified WebKit Page Loading 528+ (Nightly build) Unspecified Unspecified UNCONFIRMED P2 Minor --- 0 bruno.michel webkit-unassigned ap beidson oldest_to_newest 682320 0 bruno.michel 2012-07-30 13:18:45 -0700 Steps to reproduce: I've opened 20 tabs on the same site (same domain) and didn't close them. This web site use EventSource on each page. Actual results: The first 15 tabs are opened correctly. The 5 next show a blank page with 'Connecting...' as a title and a loader. And nothing else happened until I closed one tab, not even a timeout after several minutes. The browser used one connection for each EventSource on the 15 first tabs and hit a limit. If I increase network.http.max-connections-per-server in about:config, I don't reproduce the problem. Expected results: At least, having an error message, not just a blank page. Ideally, the browser should have not allowed the EventSource to take all the connections and could load the page.
