Hello,
I'm currently using the latest Perl module Net::Server::HTTP release 2.009
available at https://metacpan.org/pod/Net::Server::HTTP
Thanks for developing it!
It works well on Linux but I also need it to work on Windows.
For now, it is my second attempt in two years,
it doesn't offer the same stability on the Windows platform.
I'm using latest Strawberry Perl 5.30.2.1
taken at http://strawberryperl.com/
Even the oneliner is not reliable:
For example, I do this on a windows host:
perl -e "use base qw(Net::Server::HTTP); main->run()"
On a linux host I run "ab" which is a basic tool to run http connexions
and measure them:
ab -v4 -s10 -n6 http://192.168.103.24/
-v4 : verbosity level - 4 and above prints information on headers
-s10 : timeout 10 secondes
-n6 : 6 requests to perform for the benchmarking session.
...
The first time, I get those first good results:

But if I do it again or again then it finally fails with no more

I have no clue on what happens, the other side, the server, just stalls on this:
C:\Users\pc HP DV7>perl -e "use base qw(Net::Server::HTTP); main->run()"
