Has anyone figured out a way ever to check if there's an
internet connection in MetaCard?
Low-tech: Try to download a small but known url. Trap error.

I think the only way that will be technically faster than this would be
to use sockets, and make a HEAD request, rather than a GET for the url
in question.
You'd have to look up http protocol, but basically what it does it let
you get just the http headers for a page rather than the contents.
remember that getting a URL is a threaded event
Do you mean blocking? When I put a large url, the script doesn't progress
until the url data has been completely retrieved. Also, I believe Dave
Cragg has confirmed that get url is a blocking call, which is why he

How do you define very very slow? When I use:

...on a DSL connection, the answer is near instantaneous, especially with a
bogus domain/address. If you think about it, how else can you determine if
a url exists without actually trying it?
Dave,
I will try your handler. Thanks!
