mod_deflate mixes compressed and uncompressed data when SSI issues a redirect

           Summary: mod_deflate mixes compressed and uncompressed data when
                    SSI issues a redirect
           Product: Apache httpd-2.0
           Version: 2.0.44
          Platform: Sun
        OS/Version: Solaris
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: mod_deflate
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: koreth-apache@midwinter.com


This is almost certainly a variant of bug 15423, but that bug is fixed and this
problem still exists.  I'm not sure whether it's really a mod_deflate bug or a
mod_include bug.  If I have a server-parsed HTML file on an Apache 2 server that
has mod_deflate enabled for HTML content, and it includes a CGI that issues a
redirect to another HTML file, the redirected content isn't compressed, even
though the server issues a "Content-Encoding: gzip" header line.  My test case:

dozer% cat test-apache2-redir.shtml
<!--#include virtual="/cgi-bin/redirtest" --> Got to end!

dozer% cat foo.html
hiya

dozer% cat ~/apache/cgi-bin/redirtest
#!/bin/sh
echo Location: /foo.html
echo ''

dozer% ( echo 'GET /test-apache2-redir.shtml HTTP/1.1' ; \
         echo 'Accept-Encoding: gzip' ; \
         echo 'Host: dozer' ; \
         echo '' ) | nc dozer 8763 | less
HTTP/1.1 200 OK

The output (with the patch for bug 15423 applied) is correct if I don't accept
gzip encoding:

dozer% ( echo 'GET /test-apache2-redir.shtml HTTP/1.1' ; \
         echo 'Host: dozer' ; \
         echo '' ) | nc dozer 8763
HTTP/1.1 200 OK
