Any website that generates a decent traffic needs a statistic page. So how do you collect statistics?
ASP .NET knows how to sniff some information from the visitor, from basic information like the browser version to information about the support of Java Applets and ActiveX Controls.

The following is VB .NET code for displaying client information with ASP .NET:




<%

response.write("<b>Name:</b> " & Request.ServerVariables("REMOTE_HOST") & "<br />")

response.write("<b>IP:</b> " & Request.ServerVariables("REMOTE_ADDR") & "<br />")

response.write("<b>User agent:</b> " & Request.ServerVariables("HTTP_USER_AGENT") & "<br />")

response.write("<b>Language:</b> " & Request.ServerVariables("HTTP_ACCEPT_LANGUAGE") & "<br />")

response.write("<b>Browser:</b> " & Request.Browser.Browser & "<br />")

response.write("<b>Type:</b> " & Request.Browser.Type & "<br />")

response.write("<b>Version:</b> " & Request.Browser.Version & "<br />")

response.write("<b>Major version:</b> " & Request.Browser.MajorVersion & "<br />")

response.write("<b>Minor version:</b> " & Request.Browser.MinorVersion & "<br />")

response.write("<b>Beta:</b> " & Request.Browser.Beta & "<br />")

response.write("<b>Cookies:</b> " & Request.Browser.Cookies & "<br />")

response.write("<b>Frames:</b> " & Request.Browser.Frames & "<br />")

response.write("<b>Tables:</b> " & Request.Browser.Tables & "<br />")

response.write("<b>ActiveX:</b> " & Request.Browser.ActiveXControls & "<br />")

response.write("<b>Java Applets:</b> " & Request.Browser.JavaApplets & "<br />")

response.write("<b>JavaScript:</b> " & Request.Browser.JavaScript & "<br />")

response.write("<b>VBScript:</b> " & Request.Browser.VBScript & "<br />")

response.write("<b>Platform:</b> " & Request.Browser.Platform & "<br />")

response.write("<b>Crawler:</b> " & Request.Browser.Crawler & "<br />")

%>

Here is a sample result:
