<p>The <directive module="core">ServerAdmin</directive> and
|
|
<directive module="core">ServerTokens</directive> directives
|
|
control what information about the server will be presented
|
|
in server-generated documents such as error messages. The
|
|
<directive module="core">ServerTokens</directive> directive
|
|
sets the value of the Server HTTP response header field.</p>
|
|
|
|
<p>The <directive module="core">ServerName</directive> and
|
|
<directive module="core">UseCanonicalName</directive>
|
|
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 <directive module="core">ServerRoot</directive>. Be careful
|
|
about locating files in paths which are writable by non-root users.

<p>The <directive>LimitRequest</directive>*
|
|
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 <directive>RLimit</directive>* 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 <directive module="mpm_netware">ThreadStackSize</directive> directive
|
|
is used only on Netware to control the stack size.</p>
