Is there a way I can know the Processor of my web page visitor? just for collecting statisics

I read in an IBM book a ServerVariable that can do the job but didn't work:

HTTP_UA_CPU (I.E. 3+ only) Client's computer CPU type.

can anyone help

Ive never heard of any coding type getting the comps info (like cpu and ram). You would have to have like an ActiveX script to do that.

You are corrent this servervariable does exit but it has been taken off from MS since IE 4.x, and it was only reported with IE anyway so netscape etc users would always be blank. You could theoretically use a javascript function which is extremely in-accurate though. It all depends on cpu, ram, load etc. but you might wanna use it as a benchmark.
function test_cpu(force){
var d=doc;dc=d.cookie,dcr=/CpuSpeed=([^;]+);/,r=dcr.exec(dc)

if (r&&!force){
mhz = r[1]
} else {
var average,t1,t2,t,l,report=0,passes,offset=d.all?110:150

passes = 40

for (l=0;l<passes;l++){
   t1 = new Date().getTime()
   for (t=0;t<20000;t++){}
   t2 = new Date().getTime()
   report += t2-t1
}
average = report/passes

mhz = parseInt((65/average)*offset)
d.cookie = 'CpuSpeed=' + mhz + ';'
} return mhz
}
