<div class="page-header">
<h1>Responses</h1>
</div>
<p>The general form of a response is as follows:</p>
<pre class="example">code[MESSAGE]:[colon-separated list of features]</pre></p>
<table class="table table-bordered">
<tbody >
<tr>
<td>
hKEY=VALUE
</td>
<td>
Set a header. Both KEY and VALUE are full <a href=#valuespec>Value Specifiers</a>.
</td>
</tr>
<tr>
<td>
bVALUE
</td>
<td>
Set the body. VALUE is a <a href=#valuespec>Value
Specifier</a>. When the body is set, pathod will
automatically set the appropriate Content-Length header.
</td>
</tr>
<tr>
<td>
cVALUE
</td>
<td>
A shortcut for setting the Content-Type header. Equivalent to:
<pre>h"Content-Type"=VALUE</pre>
</td>
</tr>
<tr>
<td>
iOFFSET,VALUE
</td>
<td>
Inject the specified value at the offset. OFFSET can be an
integer, or "r" to generate a random offset or "a" for an
offset just after all data has been sent.
</td>
</tr>
<tr>
<td>
lVALUE
</td>
<td>
A shortcut for setting the Location header. Equivalent to:
<pre>h"Location"=VALUE</pre>
</td>
</tr>
<tr>
<td>
dOFFSET
</td>
<td>
Disconnect after OFFSET bytes. The offset can also be "r", in which case pathod
will disconnect at a random point in the response.
</td>
</tr>
<tr>
<td>
pSECONDS,OFFSET
</td>
<td>
Pause for SECONDS seconds after OFFSET bytes. SECONDS can also be "f" to pause
forever. OFFSET can also be "r" to generate a random offset, or "a" for an
offset just after all data has been sent.
</td>
</tr>

<h2>VALUEs</h2>
<h3>Literals</h3>
<p>Literal values are specified as a quoted strings: </p>
<pre class="example">"foo"</pre>
<p>Either single or double quotes are accepted, and quotes can be escaped with
backslashes within the string:</p>
<pre class="example">'fo\'o'</pre>
<p>Literal values can contain Python-style backslash escape sequences:</p>
<pre class="example">'foo\r\nbar'</pre>
<h3>Files</h3>
<p>You can load a value from a specified file path. To do so, you have to specify
a _staticdir_ option to pathod on the command-line, like so: </p>
<pre class="example">pathod -d ~/myassets</pre>
<p>All paths are relative paths under this directory. File loads are indicated by
starting the value specifier with the left angle bracket:
<pre class="example"><my/path</pre></p>
<p>The path value can also be a quoted string, with the same syntax as literals:</p>
<pre class="example"><"my/path"</pre>
<h3>Generated values</h3>
<p>An @-symbol lead-in specifies that generated data should be used. There are two
components to a generator specification - a size, and a data type. By default
pathod assumes a data type of "bytes". </p>
<p>Here's a value specifier for generating 100 bytes:
<pre class="example">@100</pre></p>
<p>You can use standard suffixes to indicate larger values. Here, for instance, is
a specifier for generating 100 megabytes:</p>
<pre class="example">@100m</pre>
<p>Data is generated and served efficiently - if you really want to send a
terabyte of data to a client, pathod can do it. The supported suffixes are:</p>
<table class="table table-bordered">
<tbody >
<tr>
<td>b</td> <td>1024**0 (bytes)</td>
</tr>
<tr>
<td>k</td> <td>1024**1 (kilobytes)</td>
</tr>
<tr>
<td>m</td> <td>1024**2 (megabytes)</td>
</tr>
<tr>
<td>g</td> <td>1024**3 (gigabytes)</td>
</tr>
<tr>
<td>t</td> <td>1024**4 (terabytes)</td>
</tr>
</tbody>
</table>
<p>Data types are separated from the size specification by a comma. This
specification generates 100mb of ASCII:</p>
<pre class="example">@100m,ascii</pre>
<p>Supported data types are:</p>
<ul>
<li>ascii</li>
<li>ascii_letters</li>
<li>ascii_lowercase</li>
<li>ascii_uppercase</li>
<li>bytes</li>
<li>digits</li>
<li>hexdigits</li>
<li>letters</li>
<li>lowercase</li>
<li>octdigits</li>
<li>printable</li>
<li>punctuation</li>
<li>uppercase</li>
<li>whitespace</li>
</ul>
