# EnableSendfile offstage
# EnableMMAP offstage
But the reality was:
The FAQ told me to uncomment those lines, but since they were already uncommented, I just turned to "on"
was that right ?
by the way, when I tried the ON and restarted apache, the problem persisted
people on my network miss elements on the page
Pardon my low knowlege on this.
