一些Asp技巧和实用解决方法
随机数:
<%randomize%>
<%=(int(rnd()*n)+1)%>
查询数据时得到的记录关键字用红色显示：
<% =replace(RS("字段X"),searchname,"" & searchname & "") %>
通过asp的手段来检查来访者是否用了代理
<% if Request.ServerVariables("HTTP_X_FORWARDED_FOR")<>"" then
response.write "您通过了代理服务器，"& _
"真实的IP为"&Request.ServerVariables("HTTP_X_FORWARDED_FOR")
end if
%>
判断上一页的来源
request.servervariables("HTTP_REFERER")
javascript: document.referrer
清除缓存，重新加载页面
<%response.expires = 0
response.expiresabsolute = now() - 1
response.addHeader "pragma","no-cache"
response.addHeader "cache-control","private"
Response.cachecontrol = "no-cache"
%>
在下拉菜单中显示年和月
检索并删除数据库里的重复记录
conn.execute("delete from table where id not in (select distinct from table)")
