how to recognize a difference between IE and FF without user-agent-string

L4 Transporter

Hi all,

does anybody know wether there is a possibility to recognize Firefox not using user-agent-string. Because some FF-user take the user-agent-string to appear as IE.

The company don't want this for safety-reasons due to the addons. Thx

Cheers Klaus

I don't think that there is another way to identify the Browser from a standard http-get operation.

Another crazy way will be to use Global Protect inside use Network to check if Firefox is installed

and deny access with HIP Profiles.

Hello kdd,

Another approach I see is to find the browser versions. Firefox is running at version 26 and IE is at version 11. There is a huge difference in numbers. This is also seen in the user agent string and if we can just filter for any particular browser and couple of its latest versions and create a custom app we should be able to narrow down more precise details between the browsers and selectively allow any one browser.

Hope this helps

Thanks

I checked the http-header-fields and i found nothing else as the user-agent-string. So it is like cat and mouse game. Everyone who knows the user-agent-string is able to let the browser appear as what ever it is wanted.

Thx for your help
