Browser Detection
Webservers know quite a bit about you
Your web browser sends a fair bit of data with each request.
More data is created on the server about which pages you access and how you move about.
Every computer that accesses the internet has an address that is unique across the entire world.
All this leaves a distinct footprint which is carefully logged and can be analysed with specialist software.
Here is a small sample of what information a web server knows about your system:
