Use directive tags on directives, rather than code tags.

    indicated by the <directive

    module="mpm_common">NumServers</directive> directive at server

    startup. Each child process creates threads as specified in the

    <code>StartThreads</code> directive. The individual threads then

    <directive module="mpm_common">StartThreads</directive> directive.

    The individual threads then

    listen for connections and serve them when they arrive.</p>

    <p>Apache always tries to maintain a pool of <em>spare</em> or

    threads to be created. For each child process, Apache assesses

    the number of idle threads and creates or destroys threads to

    keep this number within the boundaries specified by

    <code>MinSpareThreads</code> and <code>MaxSpareThreads</code>.

    <directive module="mpm_common">MinSpareThreads</directive>

    and <directive module="mpm_common">MaxSpareThreads</directive>.

    Since this process is very self-regulating, it is rarely

    necessary to modify these directives from their default values.

    The maximum number of clients that may be served simultaneously

    is determined by multiplying the number of server processes

    that will be created (<code>NumServers</code>) by the maximum

    that will be created (<directive 

    module="mpm_common">NumServers</directive>) by the maximum

    number of threads created in each process

    (<code>MaxThreadsPerChild</code>).</p>

    (<directive module="mpm_common">MaxThreadsPerChild</directive>).</p>

    <p>While the parent process is usually started as root under

    Unix in order to bind to port 80, the child processes and

    threads are launched by Apache as a less-privileged user. The

    <code>User</code> and <code>Group</code> directives are used to

    <directive module="mpm_common">User</directive> and <directive

    module="mpm_common">Group</directive> directives are used to

    set the privileges of the Apache child processes. The child

    processes must be able to read all the content that will be

    served, but should have as few privileges beyond that as

    href="../suexec.html">suexec</a> is used, these directives also

    set the privileges which will be inherited by CGI scripts.</p>

    <p><code>MaxRequestsPerChild</code> controls how frequently the

    <p><directive module="mpm_common">MaxRequestsPerChild</directive>

    controls how frequently the

    server recycles processes by killing old ones and launching new

    ones.</p>
