mod_proxy returns additional 100 Continue header

           Summary: mod_proxy returns additional 100 Continue header
           Product: Apache httpd-1.3
           Version: 1.3.24
          Platform: All
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: mod_proxy
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: fenn_b@smktech.com.au


mod_proxy in apache 1.3.24 appears to reply with an additional "HTTP 100 
Continue" header in HTTP/1.0 POST responses.

Below are responses to identical pages proxied by an apache 1.3.23 and 1.3.24 
server with identical configurations. Only occurs with HTTP/1.0 POSTs. GETs 
appear OK.

I'm not sure if this breaks RFC, but it does break every Squid proxy I can find.
