<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>
