“潜在危险的Request.Form”-获取消息

Question

I have a website and someone (every time the same) is trying to send me a message through a textbox (he adds some html code where he shouldn't) and the error is raised.

Unfortunately, all I can get are messages like this one ="...chemistry http://cra..." so it`s no way that I can understand what he try to tell me.

My question is: how I can expand that text characters length limit or handle my own error so I can get the whole message?

In your Global.asax, put an Application_Error event handler in to catch all errors that occur, which should include this one.

Sub Application_Error(object sender, EventArgs e)
{
   var ex = Server.GetLastError();
   if (ex != null)
      //Log it
}
