<p>Depending on the debug options below, the logfile may be a

limit the resources used by <span class=

+ <p>Another relevant limit to keep in mind is the maximum number

<p>If <span class="APPLICATION">Privoxy</span> is only used by
a single trusted user, limiting the number of client
connections is probably unnecessary. If there are multiple
