  While your assessment is most likely accurate, on a standard Apache install the
nokeepalive line is there but is commented out in the SSL portion of the conf
file. His complaints were associated with checkout which is SSL (or at least
should be). I am running the most current version of Apache and the SSL configs
are all in the same conf file which in the past were seperate files. While this
is not a Interchange issue per say I kinda feel it is since there is so much each
of us should be familiar with other than Interchange (perl, web servers, HTML,
SQL, ...) So maybe not an Interchange problem but the Interchaneg list should be
a good place to find a solution :)
