我昨晚部署了一个ASP.NET MVC应用程序,并发现将IIS7设置为集成模式进行部署的工作量较少.我的问题是有什么区别？使用一个或另一个有什么含义？

有时我在生产环境中遇到异常:

• 处理信息
  • 进程ID:3832
  • 进程名称:w3wp.exe
  • 帐户名称:NT AUTHORITY\NETWORK SERVICE
• 例外信息
  • 异常类型:System.Web.HttpException
  • 异常消息:服务器无法在发送HTTP标头后设置状态.
• 请求信息
  • 请求网址:http://www.myulr.pl/logon
  • 请求路径:/ logon
  • 用户主机地址:10.11.9.1
  • 用户:user001
  • 经过身份验证:是的
  • 身份验证类型:表单
  • 线程帐户名称:NT AUTHORITY\NETWORK SERVICE
• 线程信息
  • 主题ID:10
  • 线程帐户名称:NT AUTHORITY\NETWORK SERVICE
  • 冒充:假

我在测试环境中没有注意到这个错误我应该检查什么？

我正在使用ASP.NET MVC 2(候选发布者2)

我在以下代码(ContentType行)上收到错误(服务器无法在发送HTTP标头后设置内容类型.).我应该改变什么？

System.Web.HttpResponse response = System.Web.HttpContext.Current.Response;
response.ClearContent();
response.ContentType = "text/plain";
response.AddHeader("Content-Disposition", "attachment; filename=" + System.IO.Path.GetFileName(PervasiveConstants.DownloadZipLocation) + ";");
response.TransmitFile(PervasiveConstants.DownloadZipLocation);
response.Flush();
response.End();  

这是在Sharepoint 2010 webpart内.

我需要在单击按钮时呈现pdf.

我使用以下js代码:

function RenderPDf() {
            //for
            window.open("/Resources/RenderPDF", "", 'toolbar=no,titlebar=no, directories=no, location=no,status=yes, menubar=no, resizable=yes, scrollbars=yes,width=1010, height=680,left=0,top=0');
            return false;
        }

但有时我会收到以下错误:
