There is no such parameter in HTTP. What they can do is they may have some type of os fingerprinting software that they use to determine what type of os you are using. They can see what os is being used to make the http request as that information is part of the HTTP request. If the information does not match (or perhaps they see that some requests are coming from one os and other requests are coming from a different os), then they will know that you are using masquerading. -Yossi > in the later case, a transparent proxy can block http requests that do > not originate from a valid or expected IP > ( e.g. a masquarding router does not modify the IP the broser anonces as > part of the http request) > > regards > erez. > ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
