Bug #18790 for libwww-perl: LWP::Simple head does not use proxy

Subject:

LWP::Simple head does not use proxy

LWP::Simple head() method should observe ua->proxy settings, but does not appear to do so. Enough servers are broken with HEAD and I've got a workaround so I'm rating this only NORMAL. CPAN::Mini uses LWP::Simple, and uses the head($remote) method to test connectivity for early exit. Alas, the head method does not appear to (correctly) use the $ua->proxy settings. Commenting out the head-or- croak check in CPAN/Mini.pm makes the minicpan script work from behind the firewall. I'll post the work-around on use.perl.org ... libwww-perl-5.800 LWP::Simple 1.41 LWP::UserAgent 2.32 Perl 5.8.5 locally built from sources osname=aix, osvers=5.2.0.0, archname=aix config_args='-d' hint=recommended, useposix=true, d_sigaction=define usethreads=undef use5005threads=undef useithreads=undef usemultiplicity=undef useperlio=define d_sfio=undef uselargefiles=define usesocks=undef use64bitint=undef use64bitall=undef uselongdouble=undef usemymalloc=n, bincompat5005=undef OS version unchanged since Perl config -- AIX 5.2.

Can't see how it can avoid using proxy. It uses the same code path as everything else that uses $ua to process requests.

That's what I would have expected. Maybe our Proxy server is (was) busted on Head. So few things use it, and most that do silently fail-back to getting the page, it doesn't seem to be widely correctly implemented, so hardly unlikely. At this late date, I don't recall why I discounted that possibility originally. Thanks for responding, I'd forgotten I'd gotten CPAN::Mini working on AIX here at all.
