System.Web.HttpException File does not exist - Page loads just fine (ASP.NET)

Question

I\'m using Log4Net and logging everytime my ASP.NET-Application throws an error:

    protected void Application_Error(object sender, EventArgs e)
    {
              


        

Answer 1

I have same error:

There were some file references in CSS. That does not exist in directory. So it gave this error. I created Image Files, so error disappeared.

So make sure that file reference that you have given is exists in your directory

Answer 2

I bet it's the favicon.ico that Google Chrome always requests and which you forgot to include. But to be sure you could trace the request url:

protected void Application_Error(object sender, EventArgs e)
{
    Exception ex = Server.GetLastError();
    Log.Error("An error occurred", ex);
    Log.Error("Requested url: ", Request.RawUrl);
}

Now in your log file you should see:

Requested url: /favicon.ico

or something else like robots.txt when for example web crawlers attempted to crawl your site.

Answer 3

Check your HTML output of your page in case of using url with tilda "~/"

You need to use @Url.Content() to fix it
