Typically there are only a few status codes that you should see when using the WEB Access Library, which are broken down as follows:
| Group | Meaning | 
| 200-299 | Success | 
| 300-399 | Information | 
| 400-499 | Request error | 
| 500-599 | Server error | 
The most common codes are:
| Status code | Meaning | 
| 200 | URL located, transmission follows | 
| 400 | Unintelligible request | 
| 404 | Requested URL not found | 
| 405 | Server does not support requested method | 
| 500 | Unknown server error | 
| 503 | Server capacity reached | 
The full list of status codes has been extracted from the Microsoft Header file and is listed here.
