Issues regarding to Client class

Hello,

This is my first post in this forum.

I'm writing an sketch to poll an XML file from a webserver and I've successfully implemented the Client class. My issue comes when the webserver is missing, because I need to catch this exception.

Indeed, my webserver may not be available most of the time and I just need to check when it is available and then poll an XML from it.

How can I handle this situation? May I need to implement this sketch with an alternative to Client class?

Thanks in advance!
