One day I have left Site URL preference empty, and it worked for what I needed… don’t remember what it was, though.

Well, I decided to look into this before writing any actual code. In textpattern/index.php:

   if (empty($siteurl)) {
        $httphost = preg_replace('/[^-_a-zA-Z0-9.:]/', '', $_SERVER['HTTP_HOST']); 
        $prefs['siteurl'] = $siteurl = $httphost.rtrim(dirname(dirname($_SERVER['SCRIPT_NAME'])), DS);
    }
    [...]
    if (!defined('PROTOCOL')) {
        switch (serverSet('HTTPS')) {
            case '':
            case 'off': // ISAPI with IIS.
                define('PROTOCOL', 'http://');
                break;
            default:
                define('PROTOCOL', 'https://');
        }
    }

In textpattern/txp_misc.php:

function serverSet($thing)
{
    return (isset($_SERVER[$thing])) ? $_SERVER[$thing] : '';
}

This’ll work just dandy with Apache 2.4 and PHP7/FastCGI. Thanks for the heads’ up!

I’ll build a hook to make sure the domain given is actually one of mine, so people don’t try to just proxy my site for some worthless SEO/etc, but this does precisely what I want it to.

Glad it helps!

Please feel free to share your hook, we could integrate something like this (multiple site URLs) in core.

I was thinking of possibly abusing one of the custom1-3 fields and just exploding that into an array to iterate through, and throwing a 403 if no matches. I need to dig deeper through the code to ensure I follow same convention. Thanks for the tip above, it saved me several hours that I was able to squander before the storms hit! :)

I think your suggestion with a config variable in config.php, or alternatively a prefs field set up by the plugin, would be better as custom fields are attached to articles and, apart from the fact that the custom field(s) would then show up unused in each article, the article containing the relevant saved data could also be deleted.

No worries! I meant that in jest, and took it as fun as possible. :)

Me too ;-)

If you only use local references over HTTPS, browsers will complain like no tomorrow, and IE will fail to load every single resource, even with a “Yes” override, the last I checked.

Thanks for the info. I hadn’t observed that before, so I should definitely check that!

That’s simple enough. I just didn’t want to add any globals for fear that it may be a bad idea. :)
