HttpErrorsSection Class

The following table lists the possible values for the ErrorMode property. The default is 0 (DetailedLocalOnly).

ValueKeywordDescription
0 DetailedLocalOnly A detailed error response is generated only if the request comes from the local computer. If the request comes from an external address, the server generates a custom error response. Note: The value of the ExistingResponse property determines whether a detailed or custom error is generated.
1 Custom The error that the module or server generates is replaced by a custom page that you specify. This mode is useful in providing friendlier error messages to end users. Note: This setting turns off detailed errors, even for local requests.
2 Detailed A page with detailed information about the application error is displayed, and custom errors are not shown. This mode is useful for testing and debugging Web sites and applications. Note: It is a security risk to set ErrorMode to Detailed, because even remote clients will receive detailed error information that could lead to unwanted information disclosure.

The following table lists the possible values for the ExistingResponse property. The default is 0 (Auto).

ValueKeywordDescription
0 Auto The response depends on the first successful match of the following set of ordered conditions:

1. If the IHttpResponse::SetStatus method was called by using the fTrySkipCustomErrors flag, the existing response is passed through, and no detailed or custom error is shown.
2. If the ErrorMode property is set to Custom, the response is replaced.
3. If ErrorMode is set to Detailed and there is an existing response, the response is passed through.
4. If ErrorMode is set to Detailed and there is no existing response, the response is replaced with a detailed error.
1 Replace The existing response is always replaced, regardless of how SetStatus was called.
2 PassThrough The existing response is always used.
