i setup quick mojolicious server this: use mojolicious::lite; '/' => sub { $self = shift; sleep 5; #sleep here, i'm testing multiple connections @ once $self->render_text('hello world!'); }; app->start; i start with: perl mojolicious.pl daemon --listen=https://127.0.0.1:3000 problem is, if run command concurrently: time curl https://127.0.0.1:3000/ -k it seems use 1 thread requests, because if make multiple requests @ once, can take longer 5 seconds. it's if queued up. am missing here? i'm wanting use mojolicous, if can handle more 1 client @ time. mojo daemon standalone http server meant development use, not production, , runs single thread. production want either use fastcgi option , fastcgi-supporting webserver, or install nice psgi -compatible server starman or starlet or plack::handler::fcgi or fastpass , do plackup -s starman --port 3000 mojolicious.pl

i writing django application , provide optional filters , sort options results displayed. represent these optional filters , sort options using restful urls such as / /tags/tag1/ /tags/tag1/page2 /tags/tag1/by/newest-desc/ /tags/tag1/by/newest-desc/page2 etc. how should maintain existing url filters or sort options across page views? have tried using {% url 'list-view' tags=tags sort=sort-option %} in templates these cause problems when viewing pages without both tags , sort-option parameters set. this problem similar using both sort & filter on queryset looking restful url solution, not parameter or session state variable solution. any suggestions appreciated. niall sort order should get parameter should page number. they'll easier handle way. think way: /tags/tag1 indicate viewing. other 2 indicate display options.
