If i access an website, it can detect if im using a virtual machine ?
More specifically an Vmware image?
And if the website is able to.. How can i prevent it?
Thankful, Chinchila
Web servers can only tell details about the web browsers through their user agent string. Unless you're using a special web browser (unlikely) that detects that it's running in a VM, then the web server shouldn't know. In any case, UA strings are easy to change to whatever you'd like them to be, so you can always pretend to be something you're not.
