<h2>No-www</h2>
|

|
|
<p>WordPress strips the string "www" from the URLs of sites using this software. It is still possible to visit your site using the "www" prefix with an address like <em><?php echo $_POST[ 'basedomain' ] ?></em> but any links will not have the "www" prefix. They will instead point at <?php echo $nowww ?>.</p>
|
||
|
|
<p>The preferred method of hosting sites is without the "www" prefix as it's more compact and simple.</p>
|
||
|
|
<p>You can still use "<?php echo $_POST[ 'basedomain' ] ?>" and URLs like "www.blog1.<?php echo $nowww; ?>" to address your site and blogs after installation but internal links will use the <?php echo $nowww ?> format.</p>
|
||
|
|
|
||
|
|
<p><a href="http://no-www.org/">www. is depreciated</a> has a lot more information on why 'www.' isn't needed any more.</p>
