function request_path

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.
