<p>This document explains some of the directives provided by
the <a href="mod/core.html">core</a> server which are used to
configure the basic operations of the server.</p>

<p>The <code>ServerAdmin</code> and <code>ServerTokens</code>
directives control what information about the server will be
presented in server-generated documents such as error messages.
The <code>ServerTokens</code> directive sets the value of the
Server HTTP response header field.</p>
<p>The <code>ServerName</code> and
<code>UseCanonicalName</code> directives are used by the server
to determine how to construct self-referential URLs. For
example, when a client requests a directory, but does not
include the trailing slash in the directory name, Apache must
redirect the client to the full name including the trailing
slash so that the client will correctly resolve relative
references in the document.</p>

<p>These directives control the locations of the various files
that Apache needs for proper operation. When the pathname used
does not begin with a slash "/", the files are located relative
to the <code>ServerRoot</code>. Be careful about locating files
in paths which are writable by non-root users. See the <a
href="misc/security_tips.html">security tips</a> documentation
for more details.</p>

<p>The <code>LimitRequest</code>* directives are used to place
limits on the amount of resources Apache will use in reading
requests from clients. By limiting these values, some kinds of
denial of service attacks can be mitigated.</p>
<p>The <code>RLimit</code>* directives are used to limit the
amount of resources which can be used by processes forked off
from the Apache children. In particular, this will control
resources used by CGI scripts and SSI exec commands.</p>
<p>The <code>ThreadStackSize</code> directive is used only on
Netware to control the stack size.</p>
