How to Check if a User/Page is Connected to the Internet with ASP Classic for Offline Development?

Question

I'm fairly familiar with the language but this concept is a puzzle to me. I am wanting ot check if the server on which the script is running can access the internet for development so let's say if I am just working on the site offline on my own server with everything I need but internet access. Catch my drift? Thank you.

Answer 1

You can try and ping a site like this: (not tested)

url = "www.google.com"
Set objWShell = CreateObject("WScript.Shell")
Set objCmd = objWShell.Exec("ping " & url)
strPingResult = objCmd.StdOut.Readall()
set objCmd = nothing 
set objWShell = nothing

strStatus = "offline"

if InStr(strPingResult,"TTL=") > 0 then strStatus = "online"

response.write url & " is " & strStatus

response.write ".<br>" & replace(strPingResult,vbCrLf,"<br>")

不知道我是否理解正确，但是您可以为此使用Session对象/ Global.asa文件> Session_OnStart和Session_OnEnd 。
