Race Cache With Network

Veröffentlicht

We started to get "JSF1064: Unable to find or serve resource,..." log messages when migrating to Firefox 60.x

I looked into the actual TCP requests via Wireshark. The log messages correspond to HTTP requests that are canceled immediately after submitting them, before the server could send the response. I strongly suspect the "Race Cache With Network" feature which was enabled in Firefox 59 (released March 13) to be the cause.

With this feature, Firefox _may_ send requests for cached resources concurrently to the local disk cache and the actual network server. Whichever result arrives first is used - the other request is canceled (which would cause a log message about a "Broken pipe", as with other connection aborts).

The feature can be disabled in Firefox in about:config by setting network.http.rcwn.enabled to false. For me, I stopped getting log messages after setting this to false. Of course this is not a solution.

Please set property network.http.rcwn.enabled to false by default in next versions.....thanks
