		<description><![CDATA[This follow-up to my post about SSL and IP addresses covers using SSL with multiple ports on the same IP address. We often use alternate port numbers to provide test versions of a host or application, since just changing the port number keeps the ServerName the same.
It&#8217;s very straightforward to set up Apache with an [...]]]></description>

		<description><![CDATA[UW Technology offers URL Forwarding and Masking services, but there are often questions about what they are and how they differ, as well as how they&#8217;re implemented.
The basic difference is that URL Forwarding is a redirect service which can be configured to have any URL as the destination (and the browser&#8217;s URL field will change [...]]]></description>

		<description><![CDATA[A question came up at the last Web Council Meeting about protecting a directory with Pubcookie. The page loaded, but CSS, Javascript, and images didn&#8217;t. This can almost always be fixed by using PubcookieAppID in your .htaccess file.
The way Pubcookie works is it it will send multiple cookies to your browser, one for each application. [...]]]></description>

		<description><![CDATA[There are times when it&#8217;s useful to be able to check an SSL cert&#8217;s subject or expiration date. In addition, it&#8217;s useful to both check the cert file and query a service. This is useful for more than just web servers; SMTP, IMAP, and LDAP are other services which use SSL certificates. There are several [...]]]></description>

The first thing to do is to break down an email address. Everything [...]]]></description>
