Web based script to determine system information

Question

I know web based scripts can be used to identify the charactertics of vistors (display resolution, Java version, OS, architecture, render engine, etc)

But is there anything that could give me amount of system memory resident on the vistors PC?

Answer 1

Using JavaScript and the properties the browser gives you, then no. If you manage to run an ActiveX you may be able to, but I think that all the security pop ups will jump.
