<h4>ContentDisposition (Constructor)</h4>
<b>ContentDisposition</b>(<i>disposition='inline', assocs=None</i>)
<p>
            Used internally after parsing the header.
</p><p>
            Instances should generally be created from a factory
            function, such as parse_headers and its variants.
</p><a NAME="ContentDisposition.filename" ID="ContentDisposition.filename"></a>
<h4>ContentDisposition.filename</h4>
<b>filename</b>(<i></i>)
<p>
            The filename from the Content-Disposition header or None.
</p><p>
            On safety:
            This property records the intent of the sender.
</p><p>
            You shouldn't use this sender-controlled value as a filesystem
            path, it can be insecure. Serving files with this filename can be
            dangerous as well, due to a certain browser using the part after
            the dot for mime-sniffing.  Saving it to a database is fine by
            itself though.
</p><a NAME="ContentDisposition.is_inline" ID="ContentDisposition.is_inline"></a>
<h4>ContentDisposition.is_inline</h4>
<b>is_inline</b>(<i></i>)
<p>
            Return if the file should be handled inline.
</p><p>
            If not, and unless your application supports other dispositions
            than the standard inline and attachment, it should be handled
            as an attachment.
