Currently custom URLs are not passed to prerender.io.
www.yoursite.nl?param=0 will send a request without the param=0 to the prerender.io server:
return $this->client->get($this->prerenderUri . '/' . urlencode($protocol.'://'.$host.'/'.$path), compact('headers'));
Should become:
return $this->client->get($this->prerenderUri . '/' . urlencode($protocol.'://'.$host.'/'.$path.$paramsString), compact('headers'));
