lwp

问题 I am fetching some pages over the Web using Perl's LWP::UserAgent and would like to be as polite as possible. By default, LWP::UserAgent does not seamlessly handle compressed content via gzip. Is there an easy way to make it do so, to save everyone some bandwidth? 回答1: LWP has this capability built in, thanks to HTTP::Message. But it's a bit hidden.

The problem is that the server will occasionally deadlock (we're trying to figure out why) and the request will never succeed. Since the server thinks it is live, it keeps the socket connection open thus LWP::UserAgent's timeout value does us no good what-so-ever. What is the best way to enforce an absolute timeout on a request? FYI,

But HTTPS_CA_DIR=/usr/share/ca-certificates/ did
