It is possible for a CGI script to use Keep-Alive, as long as it
generates its own response body, and includes a Content-length
header. In other words, instead of just returning:

Location: wherever


You'd have to return

Status: 302 Moved
Location: wherever
Content-length: length of "some message"
Content-type: text/html

some message

Similarly with normal responses, you have to include a Content-length
response header containing the exact number of bytes in the response
body (everything after the headers and the newline ending it).

Also, Apache 1.2 will always use Keep-Alive for CGI scripts, when a
HTTP/1.1 browser makes a request (HTTP/1.0 browsers will continue to
be subjected to the above logic).
