| <h2>Summary</h2> |
| |
| <p>This module is provided strictly for compatibility with NCSA |
| httpd, and is deprecated. We recommend you use <a |
| href="mod_log_config.html">mod_log_config</a> instead.</p> |

| |
| <h2>Log file format</h2> |
| The log file contains a separate line for each refer. Each line |
| has the format |
| |
| <blockquote> |
| <em>uri</em> <code>-></code> <em>document</em> |
| </blockquote> |
| where <em>uri</em> is the (%-escaped) URI for the document that |
| references the one requested by the client, and |
| <em>document</em> is the (%-decoded) local URL to the document |
| being referred to. |

| <p>The RefererIgnore directive adds to the list of strings to |
| ignore in Referer headers. If any of the strings in the list is |
| contained in the Referer header, then no referrer information |
| will be logged for the request. Example:</p> |
| |
| <blockquote> |
| <code>RefererIgnore www.ncsa.uiuc.edu</code> |
| </blockquote> |
| This avoids logging references from www.ncsa.uiuc.edu. |

| </dl> |
| <strong>Security:</strong> if a program is used, then it will |
| be run under the user who started httpd. This will be root if |
| the server was started by root; be sure that the program is |

| <p><strong>Security:</strong> See the <a |

| for details on why your security could be compromised if the |
| directory where logfiles are stored is writable by anyone other |
| than the user that starts the server.</p> |
