<h1>mitmdump</h1>
</div>
<p><strong>mitmdump</strong> is the command-line companion to mitmproxy. It provides
tcpdump-like functionality to let you view, record, and programmatically
transform HTTP traffic. See the <em>--help</em> flag output for complete
documentation.</p>
<h1>Examples</h1>
<h2>Saving traffic</h2>
<pre class="terminal">
> mitmdump -w outfile
</pre>
<p>Start up mitmdump in proxy mode, and write all traffic to <strong>outfile</strong>. </p>
<h2>Filtering saved traffic</h2>
<pre class="terminal">
> mitmdump -nr infile -w outfile "~m post"
</pre>
<p>Start mitmdump without binding to the proxy port (<em>-n</em>), read all flows from
infile, apply the specified filter expression (only match POSTs), and write to
outfile.</p>
<h2>Client replay</h2>
<pre class="terminal">
> mitmdump -nc outfile
</pre>
<p>Start mitmdump without binding to the proxy port (<em>-n</em>), then replay all
requests from outfile (<em>-c filename</em>). Flags combine in the obvious way, so
you can replay requests from one file, and write the resulting flows to
another:</p>
<pre class="terminal">
> mitmdump -nc srcfile -w dstfile
</pre>
<p>See the <a href="features/clientreplay.html">Client-side Replay</a> section for more information.</p>
<h2>Running a script</h2>
<pre class="terminal">
> mitmdump -s examples/add_header.py
</pre>
<p>This runs the <strong>add_header.py</strong> example script, which simply adds a new header
to all responses.</p>
<h2>Scripted data transformation</h2>
<pre class="terminal">
> mitmdump -ns examples/add_header.py -r srcfile -w dstfile
</pre>
<p>This command loads flows from <strong>srcfile</strong>, transforms it according to the
specified script, then writes it back to <strong>dstfile</strong>.</p>
