| |
| <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> |
| |
| <ul> |
| <li><a href="#identification">Server Identification</a></li> |
| <li><a href="#locations">File Locations</a></li> |
| <li><a href="#resource">Limiting Resource Usage</a></li> |

| <h2><a name="identification">Server Identification</a></h2> |
| |
| <table border="1"> |
| <tr><td valign="top"> |
| <strong>Related Directives</strong><br><br> |
| |
| <A HREF="mod/core.html#servername">ServerName</A><br> |
| <A HREF="mod/core.html#serveradmin">ServerAdmin</A><br> |
| <A HREF="mod/core.html#serversignature">ServerSignature</A><br> |
| <A HREF="mod/core.html#servertokens">ServerTokens</A><br> |
| <A HREF="mod/core.html#usecanonicalname">UseCanonicalName</A><br> |
| </td></tr></table> |
| |
| <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> |

| <h2><a name="locations">File Locations</a></h2> |

| <table border="1"> |

| <a href="mod/core.html#coredumpdirectory">CoreDumpDirectory</a><br> |
| <a href="mod/core.html#documentroot">DocumentRoot</a><br> |
| <a href="mod/core.html#errorlog">ErrorLog</a><br> |

| <a href="mod/core.html#serverroot">ServerRoot</a><br> |
| </td></tr></table> |
| |
| <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> |
