timeout

Hi,

If the network connection is broken, is there a  way of setting a timeout
after which the LWP request returns?

I've seen that even if I set the timeout to 1 second, it takes much more
time until the request ends.

Thank you.

Thank you Gisle. Do you know if I can detect if there is no network
connection or if the requested domain was not found, using other methods
before trying to make the request using LWP?

Thank you.

You could try to use a module like Net::ADNS (or Net::DNS) to lookup
the hostname yourself.  If you then replace the hostname with a IP
address in the URL you pass to LWP it will bypass the gethostbyname()
step that might block.  You probably need to set the "Host" header in
the request manually if you do this.
