// Determine whether the current user has accessed the website and only records the users that have not accessed the website.
If (Request. Cookies ["IsExitsIP"] = null)
{
// Upload the TXT file every day
String fileName = string. format ("{0} {1} {2}", DateTime. now. year. toString (), DateTime. now. month. toString (), DateTime. now. day. toString ());
File file = new File (Server. MapPath ("~ /Test/"+ fileName +". txt "));
File. FileWrite (Request. UserHostName );
// Add an access tag to the user being accessed
HttpCookie cokie = new HttpCookie ("IsExitsIP ");
Cokie. Values. Add ("ip", Request. UserHostName );
Response. AppendCookie (cokie );
}
