Scripts against external data submission

When submitting a Script, someone may modify the Script to be submitted from the local machine. In this case, there is a problem of secure submission. Therefore, the Script should be submitted from the server disconnected path. Other addresses cannot be submitted:

<% Server_v1 = Cstr (Request. serverVariables ("HTTP_REFERER") server_v2 = Cstr (Request. serverVariables ("SERVER_NAME") if mid (server_v1, 8, len (server_v2) <> server_v2 thenresponse. write "<br> <center> <table border = 1 cellpadding = 20 bordercolor = black bgcolor = # EEEEEE width = 450>" response. write "<tr> <td style =" font: 9pt Verdana ">" response. write "the path you submitted is incorrect. It is forbidden to submit data from outside the site. Please do not confuse this parameter! "Response. write" </td> </tr> </table> </center> "response. endend if
