UNA installer still forgot to detect http or https

Maybe in your or other server support $_SERVER['HTTPS'], but my server not support that.

So, when we install Dolphin or UNA, we will see the wrong URL. please see install01 and install02.

I writing this program to display the environment variables supported by my server:

< ? php

echo '<PRE>';
print_r($_SERVER);
echo '</PRE><br />';

please see install03 for Server A and install04 for Server B.

You can see that there is no $_SERVER['HTTPS'] in the server variable.

therefore I use $_SERVER['HTTP_X_FORWARDED_PROTO'] to rewrite this proto()

    protected function proto()
    {
        if (isset($_SERVER['HTTP_X_FORWARDED_PROTO']))
            return $_SERVER['HTTP_X_FORWARDED_PROTO'] . '://';
        elseif ((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS']) || getenv('UNA_HTTPS'))
            return 'https://';
        else
            return 'http://';
        //return (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS']) || getenv('UNA_HTTPS') ? 'https://' : 'http://';
    }

OR

    protected function proto()
    {
        if (isset($_SERVER['HTTP_X_FORWARDED_PROTO']))
            return $_SERVER['HTTP_X_FORWARDED_PROTO'] . '://';
        else
            return (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS']) || getenv('UNA_HTTPS') ? 'https://' : 'http://';
    }

Please see install5 for the execution result of the installation.

This is the dolphin installer's index.php:

$confFirst['site_url']  = array(
    'name'    => "Site URL",
    'ex'      => "http://www.mydomain.com/path/",
    'desc'    => "Your site URL (slash at the end is required)",
    'def'     => "http://",
    'def_exp' => function () {
            $str = $_SERVER['HTTP_X_FORWARDED_PROTO'].'://'.$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF'];
            return preg_replace("/install\/(index\.php$)/", "", $str);
    },
    'check'   => function ($arg0) { return strlen($arg0) >= 10 ? true : false; }
);

P.S. When I re-edited the article iin Dolphin  (of blog) and UNA, some words in PHP and HTML disappeared and could not be used! for example:

' < PRE > ' ;

< ? php

But there is no such problem in the Dolphin Forum!
