Title: How to test if server is alive/responding ?
Post by: wvanderstek on March 06, 2009, 03:32:16 AM

We do have several servers running at service providers. We want to write a small program to see if these servers are still alive. Could anybody give a clue how to do that ?

All the servers are only listening on port 443.

Thanks,
Wilco

Hallo,


I do a fetch,

FetchServer.Fetch('https://127.0.0.1:7070')

If you get error then the server is close else is open.

It works very good for me.


Regards,
Robert

Hello Robert,

Thanks for the fast reply. Could you tell me where you FetchServer is located, caues I do get an unknown procedure label when compiling. I have looked in the dirs etc, but found nothing.

Thanks,
Wilco

Wilco,

Use the NetWebClient class.
ie in Robert's example FetchServer is the name of an object, of type NetWebClient that he's created. You can use the normal NetTalk extension to add a new object.

Also see one of the webclient examples.

Cheers
Bruce
