The username and password are separated by a single <code>:</code> and sent on the wire base64 encoded. The string is sent regardless of whether the server needs it (<em>i.e.</em>, has sent an 401 authentication needed).</dd> <dt><code>-c <var>concurrency</var></code></dt> <dd>Number of multiple requests to perform at a time. Default is one request at a time.</dd> <dt><code>-C <var>cookie-name</var>=<var>value</var></code></dt> <dd>Add a <code>Cookie:</code> line to the request. The argument is typically in the form of a <code><var>name</var>=<var>value</var></code> pair. This field is repeatable.</dd> <dt><code>-d</code></dt> <dd>Do not display the "percentage served within XX [ms] table". (legacy support).</dd> <dt><code>-e <var>csv-file</var></code></dt> <dd>Write a Comma separated value (CSV) file which contains for each percentage (from 1% to 100%) the time (in milliseconds) it took to serve that percentage of the requests. This is usually more useful than the 'gnuplot' file; as the results are already 'binned'.</dd> <dt><code>-g <var>gnuplot-file</var></code></dt> <dd>Write all measured values out as a 'gnuplot' or TSV (Tab separate values) file. This file can easily be imported into packages like Gnuplot, IDL, Mathematica, Igor or even Excel. The labels are on the first line of the file. </dd> <dt><code>-h</code></dt> <dd>Display usage information.</dd> <dt><code>-H <var>custom-header</var></code></dt> <dd>Append extra headers to the request. The argument is typically in the form of a valid header line, containing a colon-separated field-value pair (<em>i.e.</em>, <code>"Accept-Encoding: zip/zop;8bit"</code>).</dd> <dt><code>-i</code></dt> <dd>Do <code>HEAD</code> requests instead of <code>GET</code>.</dd> <dt><code>-k</code></dt> <dd>Enable the HTTP KeepAlive feature, <em>i.e.</em>, perform multiple requests within one HTTP session. Default is no KeepAlive.</dd> <dt><code>-n <var>requests</var></code></dt> <dd>Number of requests to perform for the benchmarking session. The default is to just perform a single request which usually leads to non-representative benchmarking results.</dd> <dt><code>-p <var>POST-file</var></code></dt> <dd>File containing data to POST.</dd> <dt><code>-P <var>proxy-auth-username</var>:<var>password</var></code></dt> <dd>Supply BASIC Authentication credentials to a proxy en-route. The username and password are separated by a single <code>:</code> and sent on the wire base64 encoded. The string is sent regardless of whether the proxy needs it (<em>i.e.</em>, has sent an 407 proxy authentication needed).</dd> <dt><code>-q</code></dt> <dd>When processing more than 150 requests, <code>ab</code> outputs a progress count on <code>stderr</code> every 10% or 100 requests or so. The <code>-q</code> flag will suppress these messages.</dd> <dt><code>-s</code></dt> <dd>When compiled in (<code>ab -h</code> will show you) use the SSL protected <code>https</code> rather than the <code>http</code> protocol. This feature is experimental and <em>very</em> rudimentary. You probably do not want to use it.</dd> <dt><code>-S</code></dt> <dd>Do not display the median and standard deviation values, nor display the warning/error messages when the average and median are more than one or two times the standard deviation apart. And default to the min/avg/max values. (legacy support).</dd> <dt><code>-t <var>timelimit</var></code></dt> <dd>Maximum number of seconds to spend for benchmarking. This implies a <code>-n 50000</code> internally. Use this to benchmark the server within a fixed total amount of time. Per default there is no timelimit.</dd> <dt><code>-T <var>content-type</var></code></dt> <dd>Content-type header to use for POST data.</dd> <dt><code>-v <var>verbosity</var></code></dt> <dd>Set verbosity level - <code>4</code> and above prints information on headers, <code>3</code> and above prints response codes (404, 200, etc.), <code>2</code> and above prints warnings and info.</dd> <dt><code>-V</code></dt> <dd>Display version number and exit.</dd> <dt><code>-w</code></dt> <dd>Print out results in HTML tables. Default table is two columns wide, with a white background.</dd> <dt><code>-x <var><table>-attributes</var></code></dt> <dd>String to use as attributes for <code><table></code>. Attributes are inserted <code><table <var>here</var> ></code>.</dd> <dt><code>-X <var>proxy</var>[:<var>port</var>]</code></dt> <dd>Use a proxy server for the requests.</dd> <dt><code>-y <var><tr>-attributes</var></code></dt> <dd>String to use as attributes for <code><tr></code>.</dd> <dt><code>-z <var><td>-attributes</var></code></dt> <dd>String to use as attributes for <code><td></code>.</dd> </dl></div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div><div class="section"><h2><a name="bugs" id="bugs">Bugs</a></h2> <p>There are various statically declared buffers of fixed length.
