Strange Problem

r_ganesh76 · June 3rd, 2005, 12:17 AM

Hi Experts,

I am facing a strange problem. Even thouth it is not a very serious issue, I am curious to know what it is.

I have written code in the Application_Error event in the Global.asax. In the event, I have written code to send mail to an address stating the error.

But Whenever I open the solution, I get the error mail indicating that the application_error event has been fired. This happens whenever I load the project. I dont even run the application.

Can anyone tell me what could be causing the error

Regards
Ganesh

Visual Studio sometimes calls virtual files on the application web. This could be tripping the error handler.

I know that VS requests the page "get_aspx_ver.aspx" in order to get some information from IIS. This request will result in 404 errors. Perhaps there is another request happening in the background. Check your IIS logs.

Yeah, a 404 for the get_aspx_ver.aspx page seems very logical. I have mail setup as well on errors, and I always get an email about that page not being found.

I got so tired of it I changed the code in my global.asax to not send the e-mail when a 404 for that page occurred.

Thanx Imar & Peter for your replies.

I want to ask whether this error would have any other impact after the application is deployed. Are there any chances that the error triggers once in production. I dont want the mail to be sent in the production environment. I am okey in the development environment.

No, not if it's the error we're talking about.

When VS.NET opens a project it requests that non-existent page from IIS. IIS will return a 404 message, but packed in the headers somewhere there is information about IIS and the version of .NET it is running. VS.NET needs this information to determine the framework version used.

Search Google for get_aspx_ver.aspx and read the first 5 results and follow a few links in those articles. You'll find a lot of information and ways to prevent the email from being sent.
