HTTP 0.9 Request answered with HTTP 1.1 Response





------- Additional Comments From trawick@apache.org  2004-01-21 15:54 -------
An HTTP/0.9 request would be simply:

GET /

>From RFC 1945, which describes HTTP/1.0:

"The version of an HTTP message is indicated by an HTTP-Version field
   in the first line of the message. If the protocol version is not
   specified, the recipient must assume that the message is in the
   simple HTTP/0.9 format.

       HTTP-Version   = "HTTP" "/" 1*DIGIT "." 1*DIGIT

   Note that the major and minor numbers should be treated as separate
   integers and that each may be incremented higher than a single digit.
   Thus, HTTP/2.4 is a lower version than HTTP/2.13, which in turn is
   lower than HTTP/12.3. Leading zeros should be ignored by recipients
   and never generated by senders.

   This document defines both the 0.9 and 1.0 versions of the HTTP
   protocol. Applications sending Full-Request or Full-Response
   messages, as defined by this specification, must include an HTTP-
   Version of "HTTP/1.0"
"

See that last sentence: As of HTTP/1.0 spec, if the full request message is sent
then the HTTP version must be "HTTP/1.0".  "HTTP/0.9" is not valid for a 0.9
request.

If you think Apache is responding inappropriately to a request which is not HTTP
0.9 but (presumably) an unrecognized HTTP level, that is a different issue.
