<p>The <code class="directive"><a href="./mod/core.html#serveradmin">ServerAdmin</a></code> and
|
||
<code class="directive"><a href="./mod/core.html#servertokens">ServerTokens</a></code> directives
|
||
control what information about the server will be presented
|
||
in server-generated documents such as error messages. The
|
||
<code class="directive"><a href="./mod/core.html#servertokens">ServerTokens</a></code> directive
|
||
sets the value of the Server HTTP response header field.</p>
|
||
|
||
<p>The <code class="directive"><a href="./mod/core.html#servername">ServerName</a></code>,
|
||
<code class="directive"><a href="./mod/core.html#usecanonicalname">UseCanonicalName</a></code> and
|
||
<code class="directive"><a href="./mod/core.html#usecanonicalphysicalport">UseCanonicalPhysicalPort</a></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, httpd 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 httpd needs for proper operation. When the pathname used
|
||
does not begin with a slash (/), the files are located relative
|
||
to the <code class="directive"><a href="./mod/core.html#serverroot">ServerRoot</a></code>. Be careful
|
||
about locating files in paths which are writable by non-root users.

documentation for more details.</p>

<p>The <code class="directive">LimitRequest</code>*
|
||
directives are used to place limits on the amount of resources

httpd 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 class="directive">RLimit</code>* directives
|

are used to limit the amount of resources which can be used by

processes forked off from the httpd children. In particular,

this will control resources used by CGI scripts and SSI exec
|
||
commands.</p>
|

<p>The <code class="directive"><a href="./mod/mpm_common.html#threadstacksize">ThreadStackSize</a></code>
