在Global Trust中从Global.asax重定向 [英] Redirecting from Global.asax in Medium Trust

问题描述

我正在尝试在Global.asax中的Application_Error处理程序中进行重定向.一点都不幻想.

I am attempting to do a redirect in the Application_Error handler in Global.asax. Nothing fancy at all.

private void Application_Error(object sender, EventArgs e)
{
   // ...snip...

   Server.Transfer(somePath, false);

   // ...snip...
}

这在完全信任"下很好用，但是我需要让它在中等信任"下起作用.我在此处使用的代码需要在共享托管环境中正常运行(很遗憾，我无法控制此要求).

This works great under Full trust, but I need to get it to work under Medium trust. The code I'm working on here needs to function properly in a shared hosting environment (Unfortunately, I have no control over this requirement).

但是，当我在开发环境(XP Pro/IIS 5.1)中按以下方式配置站点以进行测试时:

However, when I configure the site as follows in our dev environment (XP Pro / IIS 5.1) for testing purposes:

<system.web>
  <trust level="Medium"/>
</system.web>

它失败并出现以下错误:

It fails with the following error:

Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.**
   at System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet)

   at System.Web.HttpResponse.Flush(Boolean finalFlush)
   at System.Web.HttpResponse.Flush()
   at System.Web.HttpResponse.End()
   at System.Web.HttpServerUtility.Transfer(String path, Boolean preserveForm)

其他一些注意事项:

• 无论是从Global.asax还是从HttpModule，都会发生这种情况.
• 这也发生在Response.Redirect(somePath)中.

赞赏您可以提供的任何见解.我已经为此用Google $ a $折扣了，没什么好高兴的.

Appreciate any insight you can provide. I have Googled my a$$ off over this, and no joy.

谢谢！

推荐答案

我遇到了与您相同的问题.

I had the same problem like you.

我用过:

Response.Redirect("~/ErrorRedirectPage.aspx",false);

它工作正常.
