+ can be changed with the connection-sharing option.
+
+
+ This option has no effect if Privoxy

+
+
+ Note that a timeout of five seconds as used in the default
+ configuration file significantly decreases the number of
+ connections that will be reused. The value is used because
+ some browsers limit the number of connections they open to
+ a single host and apply the same limit to proxies. This can
+ result in a single website grabbing all the

+ Note that reusing connections doesn't necessary cause speedups.
+ There are also a few privacy implications you should be aware of.
+
+
+ If this option is effective, outgoing connections are shared between
+ clients (if there are more than one) and closing the browser that initiated
+ the outgoing connection does no longer affect the connection between &my-app;
+ and the server unless the client's request hasn't been completed yet.
+
+
+ If the outgoing connection is idle, it will not be closed until either
+ Privoxy's or the server's timeout is reached.
+ While it's open, the server knows that the system running &my-app; is still
+ there.
+
+
+ If there are more than one client (maybe even belonging to multiple users),
+ they will be able to reuse each others connections. This is potentially
+ dangerous in case of authentication schemes like NTLM where only the
+ connection is authenticated, instead of requiring authentication for
+ each request.
+
+
+ If there is only a single client, and if said client can keep connections
+ alive on its own, enabling this option has next to no effect. If the client
+ doesn't support connection keep-alive, enabling this option may make sense
+ as it allows &my-app; to keep outgoing connections alive even if the client
+ itself doesn't support it.
+
