           Summary: If backend provides a broken HTTP response line, the
                    response is returned as HTTP body
           Product: Apache httpd-2
           Version: 2.2.4
          Platform: Other
               URL: https://bugs.launchpad.net/ubuntu/+source/apache2/+bug/1
                    37233
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P2
         Component: mod_proxy
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: soren@ubuntu.com


A broken CherryPy backend (returning "HTTP/1.1 Date: blahblah" as the first
line) revealed a bug in the mod_proxy_http code. If the HTTP response line is
malformed, mod_proxy_http acts as if ProxyBadHeader was set to StartBody, i.e.
it returns the entire backend response as the body of the proxy's response.

We're tracking the issue at

That's a really good point. I suppose Apache is actually doing what it's
supposed to, so I'm closing this bug.

------- Additional Comments From serai@lans-tv.com  2007-09-11 23:51 -------
According to mod_proxy_http.c line 1268 and 1404 (trunk r574684), if the first 
line of a response is not HTTP/#.# ### (# is a digit) ( for regex: "^HTTP/
\d\.\d \d\d\d"), mod_proxy_http handles the response as HTTP/0.9.

RFC1495 http://www.ietf.org/rfc/rfc1945.txt says:

   If a client sends an HTTP/1.0 Full-Request and
   receives a response that does not begin with a Status-Line, it should
   assume that the response is a Simple-Response and parse it
   accordingly.
