Wrong Content-Length when SSI used as DirectoryIndex

           Summary: Wrong Content-Length when SSI used as DirectoryIndex
           Product: Apache httpd-2.0
           Version: 2.0.35
          Platform: PC
               URL: http://www.nanvaent.org:81/
        OS/Version: FreeBSD
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: All
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: apache-bugzilla@kolbu.com


In some cases, the Content-Length used remains the length of the file on disk, even though the 
content of the file is changed by SSIs before transfer to client. This happens only when the file in 
question is used as a DirectoryIndex, i.e. http://www.nanvaent.org:81/. If explicitly gotten, i.e. 
http://www.nanvaent.org:81/oktest.shtml, it transfers fine (presumably because the server does not 
include a Content-Length: header in that case). 
 
The weird part is that _sometimes_ it actually works... 
 
Example: 
 
In httpd.conf: 
DirectoryIndex oktest.shtml 
AddType text/html .shtml 
AddOutputFilter INCLUDES .shtml 
 
 
File /cgi-bin/oktest.cgi 
--- cut here --- 
#!/bin/sh 
echo Content-Type: text/html 
echo 
echo TeSt 
--- cut here --- 
 
File /oktest.shtml   (Note, 54 bytes long) 
--- cut here --- 
<html> 
<!--#exec cgi="/cgi-bin/oktest.cgi"--> 
</html> 
--- cut here --- 
 
Some tests with wget, the first one explicitly asking for the file: 
 
strider tmp # wget -O - -S http://www.nanvaent.org:81/oktest.shtml 
--16:57:45--  http://www.nanvaent.org:81/oktest.shtml 
           => `-'

Second test, just asking for the directory: 
strider tmp # wget -O - -S http://www.nanvaent.org:81/ 
--16:59:42--  http://www.nanvaent.org:81/
