GitHub user akravchukabto edited a comment on the discussion: XHR requests are canceled in cordova-ios after the screen is locked
_Reply I got from Norman Breau in cordova slack channel_: I don't know about that specifically but iOS is known to limit background tasks pretty significantly. I'm pretty sure all WKWebView process stuff is paused if the app goes into the background and I don't think there is any real way around that, making browser-based solutions not appealing. https://developer.apple.com/forums/thread/685525 States there are no "general purpose" background mechanism in iOS. Things just don't run in the background at all, however, specific APIs may have background modes. The NSURLSession is one API that does have a background mode so a request that has been started while the app in the foreground should continue to upload and/or download if the app goes into the background. See https://developer.apple.com/documentation/foundation/nsurlsessionconfiguration/1407496-backgroundsessionconfigurationwi?language=objc for more info on this. You won't be able to rely on the browser's fetch/XMLHttpRequest APIs, but rather use a plugin that interfaces with the native API, and that API must set up a background networking task. I've never used this so I don't know if there are any caveats but I assume it's not really a good idea to assume that every request can be a background task. My guess the cordova-plugin-advanced-http plugin doesn't do this.
