skazat has asked for the wisdom of the Perl Monks concerning the following question:

A strangely easy question today. I'm looking for a HTTP persistent connection solution (hopefully fairly high level) in Perl. My Google and search.cpan.org - fu has failed me, only finding that LWP currently (perhaps?) may not support this. Although I may be mistaken. As is not at all unusual. All the related questions on the 'monks are woefully out of date.

Looking to use HTTP keep-alive for some Amazon AWS stuff.

    HTTP is a request-based protocol, there are no "persistant connections" like they are on SQL, SMTP or FTP (where one connection may handle more than one action).

    The HTTP Keep-Alive is some kind of persistant connection, but it's limited in various ways.

  • A client may request Keep-Alive, but neither a intermediate proxy nor the server has to respect this request
  • Servers usually close Keep-Alive connections very quickly (few seconds), because they're blocking valueable server slots.
  • LWP's Keep-Alive should do the job, but there are other participants who might not support or like it.
