response.addheader
response.addheader使用实例
1.文件下载,指定默认名
Response.AddHeader("content-type","APPlication/x-msdownload");
Response.AddHeader("content-Disposition","attachment;filename=文件名.rar");
2.刷新页面
Response.AddHeader (“REFRESH”, ”60;URL=newpath/newpage.asp”)
这等同于客户机端<META>元素:
<META HTTP-EQUIV=”REFRESH”, “60;URL=newpath/newpage.asp”>
3.页面转向
Response.Status = “302 Object Moved”
Response.Addheader “Location”, “newpath/newpage.asp”
这等同于使用Response.Redirect方法:
Response.Redirect “newpath/newpage.asp”
Response.Status= “401 Unauthorized”
Response.Addheader “WWW-Authenticate”, “BASIC”
强制浏览器显示一个用户名/口令对话框,然后使用BASIC验证把它们发送回服务器(将在本书后续部分看到验证方法)。
5.如何让网页不缓冲
Response.expires = 0
Response.Expiresabsolute = Now() - 1
Response.Addheader "pragma","no-cache"
Response.Addheader "cache-control","private"
Response.CacheControl = "no-cache
