+ <para>
+ 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 <quote>grabbing</quote> all the
+ connections the browser allows, which means connections to
+ other websites can't be opened until the connections currently
+ in use time out.
+ </para>
+ <para>
+ Several users have reported this as a Privoxy bug, so the
+ default value has been reduced. Consider increasing it to
+ 300 seconds or even more if you think your browser can handle
+ it. If your browser appears to be hanging it can't.

+ While it also increases the number of connections problems
