Anyone who writes ASP programs knows that,Request. servervariables ("script_name ")Returns the relative path of the current page, for example,"Http: // localhost/BBS/post. asp", The returned result is"BBS/post. asp

Request. servervariables ("script_name ") This function is used to determine and output the path and name of the current execution file. When you change the name of an ASP file, the system automatically adapts to it to facilitate system migration. If you specify a submission page, the system will encounter an error once the file name changes.
