I have used Perl 5.00503 and Perl 5.6.1 to run a single-connection web-server for a few years now\, and have never had a problem. Recently however\, after building Perl 5.8.0 for Win32\, I ran into a severe problem. After a web page is sent across\, it gets truncated/cut-off by the time it reaches the Browser. This happens for any browser\, whether it be Netscape or IE on Windows\, or Netscape on UNIX.

I downloaded the Perl 5.8.0 binary distribution\, to see if perhaps there was a build problem on my machine in particular\, but the exact same problem occurs.

NOTE​: I also built Perl 5.8.0 for several UNIX platforms (Solaris\, DecAlpha\, HPUX\, AIX\, Linux for x86\, Linux for s390\, Reliant/Sinix\, and Sequent/Dynix) and didn't have this problem on any of those.

I thought this might be related to Ticket #16234\, but setting the environment variable "PERLIO" to "​:raw" doesn't fix the problem. The pages are actually losing A LOT of the webpages\, between 2/3 and 3/4. Any ideas on what might be the problem here?

Please see ticket #18905 instead. A more complete report\, along with configuration information\, is posted there.

I have used Perl 5.00503 and Perl 5.6.1 in combination with the HTTP​::daemon to run a single-connection webserver for a few years now\, and have never had a problem. Recently however\, after building Perl 5.8.0 for Win32\, I ran into a severe problem. After a web page is sent across\, it gets truncated/cut-off by the time it reaches the Browser.

I am sending this to "core" rather than "libraries" because the bug seems to be deeper in Perl's IO layer\, rather than a part of the HTTP/Daemon.pm module.
