+.I Note:
+because Gnome/KDE proxy settings may propagated into these variables

[Mike Mammarella, 2009/09/22 21:44:40]

"may propagate" or "may be propagated", pick one :)

+in some terminals, this variable is ignored (in preference for actual
+system proxy settings) when running under Gnome or KDE.  Use the
+command-line flags to set these when you want to force their values.
 
 .TP
 .B auto_proxy

+it should be an autoconfig URL.  But see above note about Gnome/KDE.
