Hi Stefan -

The HTTP stack built into the Condor daemons is currently setup to 
refuse http keep-alive options.  I think the reason for this limitation 
may be historical and no longer needed; let me consult on this.  If 
indeed I am correct, we can enable the http keep-alive option for the 
next developer release, ver 6.9.4 (slated for mid July).

regards,
Todd
