wwHTTP::cResultCode

Returns the HTTP result code from a request. These are HTTP spec result codes that are typically returned in the HTTP response header from the Web Server.

A valid response from a server is "200".

Note that this property might be important in some situations as wwHTTP will treat a server 500 error as a valid response. Most HTTP servers return a descriptive HTML response to a 500 (or 404) error and this response is faithfully returned by wwHTTP. So if you need to discard output from a failed request you might want to add checking for the cResultCode property.

oHTTP = CREATEOBJECT("wwHTTP")

lcFileName = "d:\temp\wwipstuff.zip"

*** Note: Invalid filename results in 404 error
oHTTP.HTTPGet("http://www.west-wind.com/files/wwipstusff.zip",,,lcFileName)

*** Check for HTTP protocol errors first
IF oHTTP.nError # 0
   ? oHTTP.nError
   ? oHTTP.cErrorMSg
   RETURN
ENDIF

*** Then check the result code
IF oHTTP.cResultCode # "200"
   ? oHTTP.cResultCode
   ?  FILETOSTR(lcFileName)   && Echo message from server
   RETURN
ENDIF

*** Display downloaded file
IF FILE(lcFileName)
   GoUrl(lcFileName)
ENDIF

Only the final header is returned so if you have a redirect the redirect result value is returned not the 302 moved header but the 200 of the final document.
