BrowsermobProxy does not capture har logs for Microsoft Edge

See original GitHub issue

Hi BrowserMob version 2.0.0

below is my script. `// start the proxy ProxyServer server = new ProxyServer(4444); server.start(); //captures the moouse movements and navigations server.setCaptureHeaders(true); server.setCaptureContent(true);

Proxy proxy = server.seleniumProxy(); DesiredCapabilities capabilities = new DesiredCapabilities(); capabilities.setCapability(CapabilityType.PROXY, proxy);

WebDriver driver = new EdgeDriver(capabilities); server.newHar(“har123”);


// get the HAR data Har har = server.getHar(); server.stop(); driver.quit(); `

My scripts work perfectly fine for chrome and firefox. When I try similar setup with MicrosoftEdge. The Scripts as normal but no Har entries are captured.“server.getHar()” returns blank.

in the log it says trying to read status from localhost<port> (not the exact error message)

My question:

  1. Does BrowserMob work with MS Edge?
  2. Does Edge needs any specific settings. My URL is a https url.
  3. Do we have a sample setup for MS edge with browsermob?

FYI, I’ve seen something similar. My scenario:

  • Using Selenium Grid (v2.53.1).
  • Asking for Edge browser (Edge v13, MicrosoftWebDriver v2.10586). Passing in BMP as the proxy in the Selenium capabilities.
  • Edge not using the proxy settings in the capabilities object, therefore putting no HTTP traffic through BMP.

Edge version: browsermob-457

What I see:

  • BMP creates the HARs correctly as and when I ask it to. I.e. the HAR file is created, and the HAR has pages for every call to newPage() I make.
  • As there is no proxy traffic coming through BMP (because Edge has not set the proxy correctly), the HARs have no request data.
  • Chrome running on the same Selenium node as Edge sets the proxy correctly and sends requests via BMP.


  • I have had to manually set the Edge proxy settings on that particular Selenium node. Traffic now gets routed via BMP.

  • open the Edge browser
  • set its proxy manually to host H and port P
  • start BMP on host H and port P
  • run tests
