Use this method to ping a Web site to check whether a valid Internet connection can be made.
You provide a fully qualified URL - preferably a static page that loads fast - to check, and you can specify a timeout value that determines how long this request runs and waits a response.
If a non-error response is returned the method returns
.T. If the request times out, or a server error occurs the function returns
.T. or .F. On error cErrorMsg is set with an error number string.
Timeout in seconds.
Timeouts are not exact and especially for connection issues where an IP Address/DNS Name exists but a server is not responding the initial connect timeout may be longer than the minimum time specified. In typical testing you can expect a minimum timeout of ~4 seconds for physical connection failures.
A fully qualified URL that you want to check.
lcServer and lcLink
For backwards compatibility the lcUrl and lcLink parameters can be used to pass a server name and server relative page path.
Example (not recommended): Http.HttpPing(5,"webconnection.west-wind.com","/download.aspx")
This routine is not a classic PING like operation, but it works only over the HTTP protocol.
oIP = CREATEOBJECT("wwHttp") *** Optionally - set any oIP Connection options oIP.cUsername = "ricks" oIP.cPassword = "supersecret" IF !oIP.HTTPPing(5,"https://west-wind.com/somepage.htm") MessageBox("No Connection") RETURN ENDIF
