It - contains document descriptions separated by blank lines, with - lines beginning with a hash character ('#') treated as - comments. A document description consists of several header - records; records may be continued on multiple lines if the - continuation lines start with spaces. The leading space will be - deleted and the lines concatenated. A header record consists of - a keyword name, which always ends in a colon, followed by a - value. Whitespace is allowed between the header name and value, - and between the tokens of value. The headers allowed are: </p> - - <dl> - <dt><code>Content-Encoding:</code></dt> - <dd>The encoding of the file. Apache only recognizes - encodings that are defined by an <code class="directive"><a href="../mod/mod_mime.html#addencoding">AddEncoding</a></code> directive. - This normally includes the encodings <code>x-compress</code> - for compress'd files, and <code>x-gzip</code> for gzip'd - files. The <code>x-</code> prefix is ignored for encoding - comparisons.</dd> - - <dt><code>Content-Language:</code></dt> - <dd>The language(s) of the variant, as an Internet standard - language tag (<a href="http://www.ietf.org/rfc/rfc1766.txt">RFC 1766</a>). An example is <code>en</code>, - meaning English. If the variant contains more than one - language, they are separated by a comma.</dd> - - <dt><code>Content-Length:</code></dt> - <dd>The length of the file, in bytes. If this header is not - present, then the actual length of the file is used.</dd> - - <dt><code>Content-Type:</code></dt> - - <dd> - The MIME media type of the document, with optional - parameters. Parameters are separated from the media type - and from one another by a semi-colon, with a syntax of - <code>name=value</code>. Common parameters include: - - <dl> - <dt><code>level</code></dt> - <dd>an integer specifying the version of the media type. - For <code>text/html</code> this defaults to 2, otherwise - 0.</dd> - - <dt><code>qs</code></dt> - <dd>a floating-point number with a value in the range 0.0 - to 1.0, indicating the relative 'quality' of this variant - compared to the other available variants, independent of - the client's capabilities. For example, a jpeg file is - usually of higher source quality than an ascii file if it - is attempting to represent a photograph. However, if the - resource being represented is ascii art, then an ascii - file would have a higher source quality than a jpeg file. - All <code>qs</code> values are therefore specific to a given - resource.</dd> - </dl> - - <div class="example"><h3>Example</h3><p><code> - Content-Type: image/jpeg; qs=0.8 - </code></p></div> - </dd> - - <dt><code>URI:</code></dt> - <dd>uri of the file containing the variant (of the given - media type, encoded with the given content encoding). These - are interpreted as URLs relative to the map file; they must - be on the same server (!), and they must refer to files to - which the client would be granted access if they were to be - requested directly.</dd> - - <dt><code>Body:</code></dt> - <dd>New in Apache 2.0, the actual content of the resource may - be included in the type-map file using the Body header. This - header must contain a string that designates a delimiter for - the body content. Then all following lines in the type map - file will be considered part of the resource body until the - delimiter string is found. - - <div class="example"><h3>Example:</h3><p><code> - Body:----xyz----<br /> - <html><br /> - <body><br /> - <p>Content of the page.</p><br /> - </body><br /> - </html><br /> - ----xyz---- - </code></p></div> - </dd> - </dl> -</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div> -<div class="section"> -<h2><a name="multiviews" id="multiviews">MultiViews</a></h2> - <p>A MultiViews search is enabled by the <code>MultiViews</code> - <code class="directive"><a href="../mod/core.html#options">Options</a></code>.
