hello
how do external counter track unique visitors via image
i'd also like to get Referrer if possible.
something like img="http://www.somecounterdomain.com/count.php?page=83599"
i'm using ASP.NET, c#
i'm aware of a user can "cheat" but would like to make that posibility minimal.
additional difficulty is that i should trach external server and can't implement c# code there.
what i can is only imlement a counter imag or smth like that. i try to use generated image. thx for answers.

A: 

Getting the 'referer' is easy and for counting unique visitors you'll need to set/check for cookies.

A: 

cookies can be faked. for example i can visit a site view 4 browsers. it's enouph to get several more visits and some bot whitch is unable to use cookies is untrackable in this situation...
infact i need results to be as true as possible.
thx 4 reply
i got another idea, what if using some flash with external api and transfered browers data? i've got some understaning of it. it'll make it a bit more difficult to fake. but what about normal users?
that site uses flash anyway.. but asking a user to install flash from nowhere does'nt seem to be pretty -_-'

Chris Taylor, thx u helped with js idea. i didn't want to use that bu that's the only way i see now. writing a cookie via .net after requesting an image. the data will be transfered except Referer (witch can be passed by QueryString) thread can be closed. I was'n registred and cleared cookies :( so i registred and can't do it
