I couldn't find anything in rfc2396 that says HTTP and http must be 
treated as equivalent, it does say they should be treated as 
equivalent, but that's a different level of specification.

3.1. Scheme Component

Just as there are many different methods of access to resources,
there are a variety of schemes for identifying such resources.  The
URI syntax consists of a sequence of components separated by 
reserved characters, with the first component defining the semantics 
for the remainder of the URI string.

Scheme names consist of a sequence of characters beginning with a
lower case letter and followed by any combination of lower case
letters, digits, plus ("+"), period ("."), or hyphen ("-").  For
resiliency, programs interpreting URI should treat upper case 
letters as equivalent to lower case in scheme names (e.g., allow 
"HTTP" as well as "http").

scheme        = alpha *( alpha | digit | "+" | "-" | "." )

Relative URI references are distinguished from absolute URI in that
they do not begin with a scheme name.  Instead, the scheme is
inherited from the base URI, as described in Section 5.2.

As anside, the second para isn't consistent with the production.
