I am trying to create a small application that will automatically check containers status and save it to a database.

If I try to go this website with Chrome: https://www.zim.com/tools/track-a-shipment and enter ZIMUSAV968904 as the container number it works.

If I try to use EO Browser to go to this page, enter the container number and click on track shipment (Same like in a regular browser), I get access is denied.

How can the website tell the difference between a regular browser an EO Browser, especially since I have not automated anything. I thought it it the User Agent but I have tried to change it (Using Fiddler) and the request was still denied.

Any help would be greatly appreciated...

Hi,

There are many subtle differences between EO.WebBrowser and Google Chrome even if they are based on the same core engine and a web page developer can actively examine those differences in order to selectively deny their services to certain application/implementations. For example, Google has been actively blocking Chromium embedder from accessing to their services. Obviously exactly what they check is guarded as a secret to avoid being circumvented. However this posts lists some ideas:

https://stackoverflow.com/questions/41801836/how-can-google-detect-a-request-is-from-a-webview

This posts discusses the difference between Android WebView and the full Google Chrome browser. However the idea is exactly the same as Android WebView is a WebView embedded inside another app, even if the WebView is implemented by Google itself.

Thanks!
