Re: stdout from scripts goes to apache logs

That being said, is there a way to output to the web page in this scenario?

CGI script runs on its own process. mod-perl basically wraps CGI script into apache process, that is why its output is automatically going to Apache log.

    Hi all,

    I'm playing around with mod_perl on apache on docker - and now I've
    finally got all the module issues sorted, I'm trying to figure out why
    when using mod_perl, the output of scripts ends up in the apache logs.

    The following configuration works, and the output of shelled scripts
    works as expected:

    <Location />
          DirectoryIndex index.pl <http://index.pl> index.html
          AddHandler cgi-script .pl
          Options +Indexes +FollowSymLinks +ExecCGI
          Require all granted
    </Location>

    If I change this to use mod_perl, all output from scripts run in web
    pages ends up in the apache log:

    <Location />
          DirectoryIndex index.pl <http://index.pl> index.html
          AddHandler perl-script .pl
          Options +Indexes +FollowSymLinks +ExecCGI
          Require all granted
    </Location>

    The perl code I'm using in the web page is as follows:
    my $cmd = "/bin/stdbuf";
    my @args = qw@ -o1 -e1 /usr/bin/speedtest-cli@;

    print '<pre class="alert">';
    my $pid = open3(0, \*READER, 0, $cmd, @args);
    while ( my $output = <READER> ) {
          print $output;
    }
    print "Speed test complete.</pre>";
    waitpid $pid,0;

    Does anyone have any clues as to why STDOUT would end up in the apache
    log and not in the web page being served when using perl-script as the
    handler?
