in reply to SOLVED: Limit URL length with Dancer/Starman

How big is this URL you request?

Is there a way to throw a 414 and avoid this behavior when Dancer running under Starman?

Sure, add a check for URI size first in line :) http://search.cpan.org/dist/Dancer/lib/Dancer/Cookbook.pod#Default_route

(untested)

any qr{.{8190}.*} => sub { status '414'; # 414 - Request-URI Too Long };

Or make a Plack::Middleware to do the check

(untested)

package Plack::Middleware::ProhibitRequestUri8190; use parent qw(Plack::Middleware); use Plack::Util; sub call { my($self, $env) = @_; my $res = $self->app->($env); if( length $res->{REQUEST_URI} > 8190 ){ Plack::Util::response_cb($res, sub { my $res = shift; $res->[0] = 414; return; }); } }

plack middleware 414 request uri too large

    Thanks.

    The default route doesn't appear to do the trick (see the updated question).

    So far I've had no luck with the plack middleware, although http://advent.perldancer.org/2010/22 looks promising (towards the bottom where they wrap the app).
