           Summary: Header directive deletes multiple headers
           Product: Apache httpd-2
           Version: 2.2.4
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: critical
          Priority: P1
         Component: mod_headers
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: marc.stern@approach.be


In case you have several headers with identical names (like Set-Cookie), which
is standard, and you use "header edit", only the first header is kept.

I reproduced this in a reverse proxymode, I'm not sure if it influences the
problem.

To reproduce:
1. Connect to an application that sends multiple Set-Cookie headers, like
SqirrelMail
2. Use the directive
      Header edit Set-Cookie "even a non existing string"  "replaced"
3. Only the first Set-Cookie header is transmitted

If you use "Header append", there is no problem.

This really screws up back-end applications when you want to edit headers.
