ngx_http_request_s是nginx中非常重要的一个结构体，贯穿于htpp请求处理的整个过程中。
下面解释了ngx_http_request_s结构体中与HTTP框架相关的重要的成员变量。

* 在接收完http头部，第一次在业务上处理http请求时，http框架提供的处理方法是ngx_http_process_request。
但如果该方法无法一次处理完该请求的全部业务，在归还控制权到epoll时间模块后，该请求再次被回调时，
将通过Ngx_http_request_handler方法来处理，而这个方法中对于可读事件的处理就是调用read_event_handler处理请求。
也就是说，http模块希望在底层处理请求的读事件时，重新实现read_event_handler方法

[2].net中页面插入CKEditor编辑器
来源: 互联网 发布时间: 2013-10-26
首先是配置，下载好。
然后把里面的文件夹放进web根目录下。
ok，现在就可以了
前台代码如下：
<head runat="server">
<title></title>
<script type="text/javascript" src=/blog_article/"ckeditor/ckeditor.js"></script>/index.html
</head>
<body>
<form id="form1" method="post" runat="server">
<div style="width:500px;height:300px;">
<asp:TextBox ID="txtContent" runat="server" TextMode="MultiLine" CssClass="ckeditor"></asp:TextBox>
<asp:Button runat="server" Text="保存" ID="btn_OK" onclick="btn_OK_Click"/>
</div>
</form>
</body>后台代码只是简单的获取到TextBox里的内容就可以了，下面包含我测试用的把数据写进一个txt格式的文本里
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
string strPath = "E:\\jin\\CompanyProject\\WebSite\\Web\\txt\\txt.Txt";
//读取:
txtContent.Text = File.ReadAllText(strPath);
}
}
protected void btn_OK_Click(object sender, EventArgs e)
{
string Data = txtContent.Text;
//string st = Request.Form.Set[form1].tostring();
string Data2 = Request.Form[txtContent.Text.ToString()];
string strContent = Data;
string strPath = "E:\\jin\\CompanyProject\\WebSite\\Web\\txt\\txt.Txt";//如: D:/Text/File.Txt
File.WriteAllText(strPath, strContent);//保存文件
}效果如下：

解决办法：
8.5版本的Websphere，需要 “cglib-nodep-2.2.2.jar” 替换 ekp/web-inf/lib下的“cglib-2.2.2.jar”文件
原因是：cglib-2.2.2.jar 可以与 asm-3.3.1.jar 搭配使用管理bean文件，但是"asm-3.3.1.jar"不可以与“asm-4.0.jar”搭配使用，正是因为Websphere 8.5 自身带了“asm-4.0.jar”造成的。
在其他应用服务器下不会有问题。
出现的异常是：重写了某个final方法，这个方法正是 asm-4.0.jar与asm
