<p>This document explains some of the directives provided by the

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
|
|

|
|
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>
