I am checking for browser type and version on my .aspx page, and I have one visitor that can't
access the page because his IE6 browser is returning an "Unknown" when I do my check.

I am using IE6 (as are a few hundred others) and none of us is having an access problem; only this
one person.

Can someone tell me why this one visitor would be having this problem? I don't know his OS, yet.

Thanks,
George
 
More info pertaining to that:

My javascript visitor tracking service is also reporting that visitor as "Browser and OS Unknown,"
even though javascript is enabled on the visitors PC.

Check the HTTP Request "User Agent" header field, i.e. Request.UserAgent.
If the browser information is not there (and it's only/ultimately found
there), then the user's (proxy) server has not included/stripped such field
from the HTTP Request.
 
there are a lot of ways for the agent header to be modified, as a lot of
proxies/firewall will strip for you. its also not a very reliable way to
detect browser. as the asp.net browser detect only uses the agent heard, it
is very weak. for instance, its properties VBScript and Javascript will
return turn even is scripting is turned off by the user.

Peter and Bruce,

Thanks, I appreciate your input. I suspect this visitor is using some kind of a proxy.
