Using Mojolicious Non Blocking Page Fetch within Apache preforked mod

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

We fetch multiple web pages in our mod_perl handler. To send concurrent requests we have been using Parallel::ForkManager. Apparently a forked environment is not recommended for using this module. See http://search.cpan.org/~szabgab/Parallel-ForkManager-1.06/lib/Parallel/ForkManager.pm#BUGS_AND_LIMITATIONS . Our findings, for concurrent requests (ab -n100 -c5) with and without this module, confirm this.

We are considering Mojolicious for non blocking page fetches. However we are not sure if that has limitations too when used within Apache's pre-forked mod_perl handler. Any arguments against using it could help us skip the migration early. Does Mojolicious's non blocking web page fetch interfere in anyway with Apache's mod_perl handlers?

Thanks

Usually Mojo is used as a persistent process listening on an internal port. Requests are handled via Apache using mod_proxy or some other intermediary (e.g., HAProxy, Varnish, or Nginx). I would not recommend this approach with mod_perl if you can help it.	[reply]

Mojolicious docs say use mod_proxy, then you can have the websockets ... because to use mod_perl you'd run mojo through Plack::Handler::Apache2 and plack doesn't websockets I don't know where Plack::App::WebSocket fits in or could be made to work with ...Apache2 and Mojo, but it came out before 2014, which is time of https://groups.google.com/forum/?_escaped_fragment_=topic/mojolicious/O792BOP9wUg#!topic/mojolicious/O792BOP9wUg, and "them mojo guys" would have probably noticed if it worked for this purpose (:but it doesn't hurt to ask :)	[reply]

Many thanks. I was hoping that I could just replace the Mechanize calls by Mojolicious's. It looks like more work may be needed. I've asked on the forum to confirm this though.	[reply]
