各位，小弟我在编写一个网上书店系统，在实现新用户注册时，当输入全部注册信息后，一点“提交”，便会出现“http标题已经写入到客户浏览器，任何http标题的修改必须在写入页内容之前“的错误提示。错误编号：‘ASP 0156:80004005'.请问是什么原因？另外哪里可以找到有关ASP错误提示的解释的文章？谢谢！reg.asp的部分源码如下：
1dim action
2action=request.QueryString("action")
1select case action
2case ""
1<form action="reg.asp?action=yes" method="post" name="form1">
2<td height="36"><div align="center">
3<input name="Submit" type="submit" value="我 同 意"/>
4 <input name="Submit2" onclick="location.href='reg.asp'" type="button" value="我 不 同 意"/>
5</div></td></form>
1case "yes"
1<form action="reg.asp？action=save" method="post" name="userinfo">
2<input <input="" name="Submit1" onclick="return " type="reset" value="重 置"/>&
case "save"
1<!--#include file="md5.asp"-->
call saveuser()

sub tiaoyue()
set rs=server.CreateObject("adodb.recordset")

response.Write trim(rs("regtiaoyue"))
rs.Close
set rs=nothing
end sub
sub saveuser()
if session("regtimes")=1 then
response.Write "<div align="center"><font color="red" size="60">对不起，您刚注册过用户。<br/>请稍后再进行注册！</font></div>"
response.End

if not rs.eof and not rs.bof then

前面加上<%response.buffer=true
1\---------------------------------------------------------------
2
3right
4
5頁首加上```
6Response.Buffer=True
---------------------------------------------------------------
在这页的最前面加
1Response.Buffer=True
因为以前的默认buffer=true,而你的IIS默认为false,所以要加
---------------------------------------------------------------
给小妹妹我分哦~！reg.asp的最前面写上``` response.buffer=true
1\---------------------------------------------------------------
2
3在使用cookies时，写cookies时必须是在没有向浏览器写数据之前，你的
4response.Cookies("bookshop")("username")=trim(request("username"))
5response.Cookies("bookshop").expires=date+1
6这两句之前有东西写到浏览器了，所以产生上面的错误，解决办法是
7在页面开始加
response.buffer=true
1\---------------------------------------------------------------
2
response.buffer=true
1response.end
2response.fuls 来决定是要送出或取消，
3一般有转向操作时都要先缓存的。因为你不知道，后来会程序怎么样。</form>
