FAQ: What error codes can be returned from a remote Web server?

A Web server returns a status code for every request. The status codes returned are categorized as follows:

• Informational 1xx
• Successful 2xx
• Redirection 3xx
• Client Error 4xx
• Server Error 5xx

AspTear doesn't show 1xx, 2xx or 3xx (unless .FollowRedirects is set to False) status codes. Errors that are returned due to client or server error range in the 4xx and 5xx regions.

For more information on status codes and what they mean, please see Request For Comment RFC 2616, section HTTP Status Code Definitions.

It is also recommended that you review the .Headers property for more information on the HTTP status code returned by the server for your request.
