    <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 >

                </td>
                <td>
                    Set a header. Both KEY and VALUE are full <a href=#valuespec>Value Specifiers</a>.

                </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>

                <td>
                    A shortcut for setting the Content-Type header. Equivalent to:

                <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>
                    Disconnect after OFFSET bytes. The offset can also be "r", in which case pathod
                    will disconnect at a random point in the response.

                <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.

<div class="page-header">
   <h1>Components</h1>
</div>

    <a id="valuespec"></a>
    <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">&lt;my/path</pre></p>

    <p>The path value can also be a quoted string, with the same syntax as literals:</p>

    <pre class="example">&lt;"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>
