I suppose these problems occur without CGI or SSI, but only with FTOCL
as an external filter command.
DeleGate on Windows tries to shutdown the TCP connection to the client
when it is running with FTOCL filter, on the end of response without
Keep-Alive.
The shutdown can be suppressed with the following option:

  SOCKOPT=noshut


 |    cat filter.cfi
 |
 |    #!cfi
 |    Content-Type: text/plain
 |    Header-Filter: filter.bat
 |    Body-Filter: filter.bat
 |
 |    cat ssi.shtml
 |
 |    <!--#exec cmd="cgi.bat" -->
...
 |    dg9_2_0.exe DGROOT=tmp -f RELAY=no STLS=-FCL \
 |    ADMIN=dummy -P8000 SERVER=http -v \
 |    MOUNT="/ssi/* file:*" FTOCL=filter.cfi
 |
 |=> "curl http://localhost:8000/ssi/ssi.shtml" = filter apparently not  
 |invoked

It is just because the Content-Type of the SHTML is not text/plain but
text/html.  You can change the Content-Type of the output of SHTML with
META tag as this:

  <META HTTP-EQUIV=Content-Type CONTENT="text/plain">

Cheers,
Yutaka
