function request_path in Drupal 7

Returns the requested URL path of the page being viewed.

Examples:

• http://example.com/node/306 returns "node/306".
• http://example.com/drupalfolder/node/306 returns "node/306" while base_path() returns "/drupalfolder/".
• http://example.com/path/alias (which is a path alias for node/306) returns "path/alias" as opposed to the internal path.
• http://example.com/index.php returns an empty string (meaning: front page).
• http://example.com/index.php?page=1 returns an empty string.

    // very early in the bootstrap process, so the original value is saved in
    // $path and returned in later calls.

    // explicitly provided in the URL, or because the server added it to
    // $_SERVER['REQUEST_URI'] even when it wasn't provided in the URL (some
    // versions of Microsoft IIS do this), the front page should be served.

  // assigned to $_GET['q'] with a slash. Moreover we can always have a trailing
  // slash in place, hence we need to normalize $_GET['q'].
