_isUrlInternal method in Mage_Core_Controller_Varien_Action failing due to port number

Question

i am implementing the currency switcher on my 1.5.1.0 CE site. it's a fairly straightforward implementation, but for some reason, once i select a currency, i get redirected to the homepage rather than the page i was one.

i narrowed it down to the fact that the method _isUrlInternal is failing due to the port number being in the referring url. i'm definitely not using port numbers explicitly (using the standard 80/443).

can anyone think of a reason why it would be evaluating port numbers?

Answer 1

for some reason, magento doesn't seem to include 443 as a default port (or doesn't check for it).

getCurrentUrl() in the core helper:

$port = $request->getServer('SERVER_PORT');
if ($port) {
  if ($port == Mage_Core_Controller_Request_Http::DEFAULT_HTTP_PORT) {
    $port = '';
  }
  else {
    $port = ':' . $port;
  }
}
