IPv6 related garbage in $_SERVER['HTTP_HOST']

Hiawatha version: v7.3
Operating System: Windows Vista
I use the following PHP script to find out if a web server is spewing garbage.
<?php
echo '<html><head><title>Plain garbage</title></head><body><p><tt>';
echo 'SERVER_SOFTWARE: ' . $_SERVER['SERVER_SOFTWARE'];
echo '<br/>';
echo 'PHP version: ' . phpversion();
echo '<br/><br/>';
echo 'SERVER_NAME: ' . $_SERVER['SERVER_NAME'];
echo '<br/>';
echo 'HOSTNAME: ' . $_SERVER['HOSTNAME'];
echo '<br/>';
echo 'HTTP_HOST: ' . $_SERVER['HTTP_HOST'];
echo '<br/>';
echo 'SERVER_ADDR: ' . $_SERVER['SERVER_ADDR'];
echo '</tt></p></body></html>';
?>
This is what I got back.
SERVER_SOFTWARE: Hiawatha v7.3
PHP version: 5.3.3
SERVER_NAME: localhost
HOSTNAME:
HTTP_HOST: [2001
SERVER_ADDR:
It looks like Hiawatha is clipping everything off after the first colon. The value of HTTP_HOST should have been [2001:470:a:18f::2]. This bug also appears in version 6.17.1 as installed with Puppy 5.1.1.

I will leave my web server up until about 4pm (PDT) today. The URL is http://[2001:470:a:18f::2]/plaingarbage.php.

I don't have a properly working IPv6 connection with the internet. So, I can't look at the webpage via the given URL.

Thanks for reporting the issue. It will be fixed in the next release. In the meantime, you can use the following fix. In serverconfig.c in get_hostrecord(), you can remove the following code:
if ((dots = strchr(hostname, ':')) != NULL) {
*dots = '\0';
}
