+
+    Each part of a URL, e.g. the path info, the query, etc., has a
+    different set of reserved characters that must be quoted.
+
+    RFC 2396 Uniform Resource Identifiers (URI): Generic Syntax lists
+    the following reserved characters.
+
+    reserved    = ";" | "/" | "?" | ":" | "@" | "&" | "=" | "+" |
+                  "$" | ","
+
+    Each of these characters is reserved in some component of a URL,
+    but not necessarily in all of them.
+
+    By default, the quote function is intended for quoting the path
+    section of a URL.  Thus, it will not encode '/'.  This character
+    is reserved, but in typical usage the quote function is being
+    called on a path where the existing slash characters are used as
+    reserved characters.
