# Define own start my $orig_start = \&Mojo::UserAgent::start; *Mojo::UserAgent::start = sub { my ($ua, $tx, $cb) = @_; $tx->{__nb} = 1 if $cb; $orig_start->(@_); }; my $ua = Mojo::UserAgent->new; $ua->on(start => sub { my ($ua, $tx) = @_; warn "Non-blocking" if exists $tx->{__nb}; } ); On 2 October 2015 at 06:32, Kit Peters <kitbroadb...@gmail.com> wrote: > I'm told by jberger on #mojo that you can't.
