验证码在服务器端判断时的问题
/*   以下是服务器端判断用的代码   */

If   Session( "GetCode) ")   <>   Request.Form( "guestCode ")   Then
'Response.Write( "Session= "&Session( "GetCode "))
'Response.Write( " <br   /> Request= "&Request.Form( "guestCode "))
Session( "GetCode) ")   =   " "
Response.Write( " <script   type= 'text/JavaScript '> ")
Response.Write( "alert( '验证码输入不正确! ');history.back() ")
Response.Write( " </script> ")
Response.End()
End   If

/*   调试输出时发现,Session和Request中的值是一模一样的,但就是会提示验证码不正确!!!   */


怎么回事啊?

备注:
页面使用UTF-8编码:

<%@LANGUAGE= "VBSCRIPT "   CODEPAGE= "65001 "%>
<%Session.CodePage= "65001 "%>
<%Response.CodePage= "65001 "%>
<!DOCTYPE   html   PUBLIC   "-//W3C//DTD   XHTML   1.0   Transitional//EN "   "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ">
<html   xmlns= "http://www.w3.org/1999/xhtml ">
<head>
<meta   http-equiv= "Content-Type "   content= "text/html;   charset=utf-8 "   />

加个trim试试
