<h3>Summary</h3>
<p>
<code class="module"><a href="../mod/mod_sed.html">mod_sed</a></code> is an in-process content filter. The <code class="module"><a href="../mod/mod_sed.html">mod_sed</a></code> filter implements the <code>sed</code> editing
commands implemented by the Solaris 10 <code>sed</code>
program as described in the <a href="http://www.gnu.org/software/sed/manual/sed.txt">manual
page</a>. However, unlike <code>sed</code>, <code class="module"><a href="../mod/mod_sed.html">mod_sed</a></code> doesn't take data from
standard
input. Instead, the filter acts on the entity data sent between client and
server. <code class="module"><a href="../mod/mod_sed.html">mod_sed</a></code> can be used as an input or output filter. <code class="module"><a href="../mod/mod_sed.html">mod_sed</a></code> is a
content filter, which means that it cannot be used to modify client or
server http headers.
</p>
<p>
The <code class="module"><a href="../mod/mod_sed.html">mod_sed</a></code> output filter accepts a chunk of data, executes the <code>sed</code> scripts on the data, and generates the output which is passed to the next filter in the chain.
</p>
<p>
The <code class="module"><a href="../mod/mod_sed.html">mod_sed</a></code> input filter reads the data from the next filter in the chain, executes the <code>sed</code> scripts, and returns the generated data to the caller filter in the filter chain.
</p>
<p>
Both the input and output filters only process the data if newline characters are seen in the content. At the end of the data, the rest of the data is treated as the last line. Lines greater than 8MB in length result in an error.
