In addition to these, the header lines recieved from the client, if
any, are placed into the environment with the prefix HTTP_ followed by
the header name. Any - characters in the header name are changed to _
characters. The server may exclude any headers which it has already
processed, such as Authorization, Content-type, and Content-length. If
necessary, the server may choose to exclude any or all of these
headers if including them would exceed any system environment limits.
An example of this is the HTTP_ACCEPT variable which was defined in
CGI/1.0. Another example is the header User-Agent.
There is no indication here that the header name should be turned into
all capital letters, as seems to have been done in all the examples.
True, it is a convention that environment variables be represented in all
caps, but "foo" and "FOO" are distinct and a literal interpretation of
the spec would indicate that the env variable should be called HTTP_Accept.
In summary, I know what was *meant*, but I'd much prefer something
unambiguous. Does such a beast exist?
