Status-Line without Reason-Phrase might add extra line feed.

           Summary: Status-Line without Reason-Phrase might add extra line
                    feed.
           Product: Apache httpd-1.3
           Version: 1.3.26
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: mod_proxy
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: puckman@taglab.com

On a ProxyPass if mod_proxy receives a response without a Reason-Phrase, formatted like:
"HTTP/1.1 200 "
(The trailing space is important)

It will in this scenario return a header with an extra LF after the Status-Line but before any headers.

My test scenario is a server running on port 1234 ProxyPassing everything to port 80 where I have a mod_jk hooked up to a Coyote JK 2 to Tomcat 4.1.12.
(Coyote JK 2 is the one sending these kind of responses).

And for you hex junkies:
This is listening on the loopback interface on port 80. Notice the space after 200.

And this is the result from port 1234. Notice the extra 0a, where did it come from?
