"Rewrite all URLs to point to a single source" doesn't work with Subfolder Domain module

I've been looking in the code and I found the problematic function: domain_get_path($domain)

Subfolders Domain creates the subdomains at {domain}.subdomain like "example.com/subfolder1" and "example.com/subfolder2". I create a new node "node/1", published in both subdomains but sourced to "example.com/subfolder1".

When I follow the link to "node/1" from "example.com/subfolder2", Domain Access changes $base_url, so it effectively points to a single source, as follows (simplified):

domain_get_path() @ domain.module:
$url = parse_url($base_url);
$path = 'http://' . $domain['subdomain'] . $url['path'];

domain_url_outbound_alter() @ settings_custom_url.inc:
$domain[$nid] = domain_get_node_match($nid); //It contains $path as ['path'].
$options['base_url'] = $domain[$nid]['path'] . '/';

That way code ends adding the old path "subfolder2/node/1" to the new domain "example.com/subfolder1", endlessly making subfolders like this: example.com/subfolder1/subfolder2/node/1

My initial suggestion would be commenting $url['path'] in the $path variable assignation. That works for me but it might break other use cases I'm not thinking about.

Attaching better thought patch.

I think there's no way to know if $base_url should be rewritten after this function has changed it. An editor could create a node alias with name subfolder2 inside domain subfolder1.

Check these URL which Domain Access will output, despite meaning different things. Let our current domain be example.com/subfolder3:

example.com/subfolder1/subfolder2
Meaning: Node "subfolder2" is inside the new domain "example.com/subfolder1".

example.com/subfolder1/subfolder2
Meaning: Node "subfolder1/subfolder2" inside new domain "example.com".

Subfolders Domain would read the new path. What is going to do? Domain Access is telling it "absolute path for a domain" is the path of the URL.

Just as a note, $base_path is not affecting in this rewrite issue. What is being changed is $base_url.

I've been "playing" with hook_domain_load() until now, and I could more or less fix the issue by adding the following line of code:
$domain['path'] = domain_check_scheme($domain['scheme']) . '://' . $domain['subdomain'];

But then I needed a more difficult fix for forms and I didn't find comfortable to remove the path from them.

So I discovered way that I think should be a better solution for both modules:
$url['path'] in function domain_get_path() becomes request_path().
$action['path'] in function domain_form_alter() becomes "/".request_path().
Everything in domain.module.

In my opinion, this would indeed simplify path parsing and make it more robust. If this idea makes @agentrickard more comfortable, I can provide a more in depth patch.
