HarLog/HarFile empty IE11

[karim-nabli]

Hi, Env: Win Server 2016 - IE11 - Java 8- bmp 2.1.5 - Selenium 3.12.0 I have set up browsermob proxy as following:

            BrowserMobProxy proxy = new BrowserMobProxyServer();
// proxy.setHarCaptureTypes(CaptureType.getAllContentCaptureTypes());
            Set<CaptureType> set = CaptureType.getAllContentCaptureTypes();
            set.addAll(CaptureType.getBinaryContentCaptureTypes());
            set.addAll(CaptureType.getHeaderCaptureTypes());
            set.addAll(CaptureType.getNonBinaryContentCaptureTypes());
            set.addAll(CaptureType.getRequestCaptureTypes());
            set.addAll(CaptureType.getResponseCaptureTypes());
            proxy.setHarCaptureTypes(set);          
            proxy.setTrustAllServers(true);
            proxy.start(0);
            Proxy seleniumProxy = ClientUtil.createSeleniumProxy(proxy);    
            seleniumProxy.setHttpProxy("127.0.0.1:"+proxy.getPort());
            seleniumProxy.setSslProxy("127.0.0.1:7357");
                        proxy.newHar();

after creating IE webdriver instance

 InternetExplorerOptions ieOption = new InternetExplorerOptions();
ioOption.setCapability(CapabilityType.PROXY, seleniumProxy)
        ieOption.setCapability(InternetExplorerDriver.IE_USE_PER_PROCESS_PROXY, true);
        ieOption.setCapability("ie.setProxyByServer", true);
        ieOption.setCapability(InternetExplorerDriver.IE_ENSURE_CLEAN_SESSION, true);   
 ieOption.setCapability(InternetExplorerDriver.INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS, true);
        ieOption.setCapability(InternetExplorerDriver.INITIAL_BROWSER_URL, "http://localhost:7357");
        ieOption.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
        ieOption.setCapability(CapabilityType.BROWSER_NAME, DesiredCapabilities.internetExplorer().getBrowserName());

the I create webdriver object, I open page in http localhost, so far so good, click event works fine. (manually I was able to see the http traffic) from trace

Well, it is Microsoft - ie- edge webdriver issue: they don't support proxy capability, in other word ioOption.setCapability(CapabilityType.PROXY, seleniumProxy) has no impact. It wont tell the webdriver to use a proxy. reference: https://docs.microsoft.com/en-us/microsoft-edge/webdriver in W3C WebDriver section, there is the line Proxy Configuration | "proxy" | Not Supported | N/A the update since 6 June 2018. There was an issue in Nov 2015 raised for similar problem : https://developer.microsoft.com/en-us/microsoft-edge/platform/issues/5468949/ So microsoft people knows about this problem for more than 2 years but they have done nothing related to that.
