How to capture all requests made by page in webdriver? Is there any alternative to Browsermob?

I found a google groups discussion on the topic. These links look like promising alternative to Browsermob:

• A Selenium CaptureNetworkTraffic Example in Java
• HOWTO: Collect WebDriver HTTP Request and Response Headers
• Automating the Capture of Web Timings with Selenium 2

There is an alternative with firefox ver 42+, there is addon called Firefox HarExport

File harExportApi = new File(System.getProperty("user.dir")
                     + "/src/main/resources/firebug/harexporttrigger-0.5.0-beta.7.xpi");

netExportProfile.addExtension(harExportApi);
netExportProfile.setPreference("extensions.netmonitor.har.enableAutomation", true);
    netExportProfile.setPreference("extensions.netmonitor.har.contentAPIToken", "test");
    netExportProfile.setPreference("extensions.netmonitor.har.autoConnect", true);

cap.setCapability(FirefoxDriver.PROFILE, netExportProfile);

and running following script will give us all the request responses

 String getHarLogScript = "var options = {\n" +
                "    token: \"test\",\n" +
                "    getData: true,\n" +
                "    title: \"my custom title\",\n" +
                "    jsonp: false,\n" +
                "  };\n" +
                "\n" +
                "  HAR.triggerExport(options).then(result => {\n" +
                "    var har = JSON.parse(result.data);\n" +
                "\n" +
                "    // Use performance.timing to provide onContentLoad\n" +
                "    +
                "     +
                "    var t = performance.timing;\n" +
                "    var pageTimings = har.log.pages[0].pageTimings;\n" +
                "    pageTimings.onContentLoad = t.domContentLoadedEventStart - t.navigationStart;\n" +
                "    pageTimings.onLoad = t.loadEventStart - t.navigationStart;\n" +
                "\n" +
                "    window.HarEntries=har.log.entries\n" +
                "\n" +
                "    console.log(\"HAR log (\" + result.data.length + \") \", har.log);\n" +
                "  }, err => {\n" +
                "    console.error(err);\n" +
                "  });"

LOG.info("Loading HAR log entries object into browser HarEntries object");
SeleniumUtils.executeScript(driver, getHarLogScript);

harEntries = ((List<Object>) SeleniumUtils.executeScript(driver, "return window.HarEntries"));

I've been working recently on this kind of proxy. Project is pretty fresh, I'm still working on documentation but it may be worth checking. Sources and examples are here

1. Add dependency to your project

    <dependency>
       <groupId>com.moxproxy</groupId>
       <artifactId>moxproxy.core</artifactId>
       <version>1.0.2</version>
    </dependency>

2. Start proxy

    MoxProxy proxy = LocalMoxProxy.builder()
                .withPort(89)
                .build();
    proxy.startServer();

3. Setup selenium webdriver to use proxy on localhost with port 89 and run test

4. Collect traffic

    List<MoxProxyProcessedTrafficEntry> requestTraffic = proxy.getAllRequestTraffic();
    List<MoxProxyProcessedTrafficEntry> responseTraffic = proxy.getAllResponseTraffic();

Beside collecting traffic proxy provides posibility to modify requests and responses - details on github
