The essence of the Cache Controller pattern is the Proxy pattern. The Cache Controller pattern is a proxy to Asynchronous and implements the interface exposed by Asynchronous. The implementation of the Proxy pattern for the Cache Controller pattern is the implementation of a caching strategy. The focus of this section will be the definition and explanation of that caching strategy. There are two ways to implement caching: let the Internet infrastructure do as much as possible for you, or write code to help the Internet infrastructure do its work. As much as I find writing a caching algorithm interesting and fun, doing so would be a waste of time. Doing your own caching is hard because so many elements in the HTTP request chain are already caching data that you have a good chance of re-caching already cached data. By caching yet again, you are providing no added value.

First, we use IIS to create a certificate request, which is simply a text file containing some encrypted text that is unique to our server, containing information about our firm and the website we want to secure. This request is then sent to a commercial CA, such as VeriSign or Thawte, or uploaded to an in-house Certificate Server.

Letting the Internet infrastructure manage the caching is called using the HTTP Expiration model. There are two ways to control the caching by using the Internet infrastructure: adding HTML tags or adding HTTP identifiers. When you want to use HTML tags to control the cache, the following HTML uses the necessary HTML tags:

<html> <head> <title>Hanging Page</title> <meta http-equiv="Cache-Control" content="max-age=3600"> <meta http-equiv="Expires" content="Tue, 01 Jan 1980 1:00:00 GMT"> </head> <body> ... The HTML tag meta has two attributes, http-equiv and content, that are used to mimic HTTP identifiers. The problem with using HTML meta tags is that they are intended to be consumed by a web browser. It is not possible to add the meta tag to an XML data stream. Therefore, it is not possible to use HTML-based cache control tags when streaming data other than HTML. The second way to control caching by using the Internet infrastructure is to generate a set of HTTP tags, as illustrated by the following HTTP request result: HTTP/1.1 200 OK Cache-Control: Public, max-age=3600 Expires: Wed, 10 Aug 2005 10:35:37 GMT Content-Type: text/html;charset=ISO-8859-1 Content-Length: 39 Date: Wed, 10 Aug 2005 09:35:37 GMT E B V N Server: Apache-Coyote/1.1 <html><body>Hello world</body></html> The HTTP identifiers Cache-Control and Expires manage how the page is supposed to be cached. The Cache-Control identifier specifies a caching of the content for 3600 seconds, or one hour. The Expires identifier defines when the retrieved content is considered expired. Both identifiers make it possible for proxies or browsers to cache the HTTP-retrieved content by using the HTTP Expiration model. When used in the context of a script, the HTTP identifiers can be programmatically generated by using the following ASP.NET code: <%@ Page Language = "C#" %> <%@ Import Namespace="System" %> <% Response.Cache.SetExpires(DateTime.Now.AddMinutes( 60 ) ) ; Response.Cache.SetCacheability(HttpCacheability.Public) ; %> <html> <head> <title>Cached Page</title> </head> <body> Hello world! </body> </html>

Caution Although you can use a Certificate Server to issue certificates for testing or internal SSL use, for

Using .NET, the methods SetExpires and SetCacheability will add the Expires and Cache-Control identifiers. To achieve the same effect by using a Java servlet, you would use the following code: import import import import javax.servlet.http.*; javax.servlet.*; java.io.*; java.util.*;

Summary

production extranets the use of a commercial certificate authority is preferred because your clients will expect certificates issued by a known and trusted third party.
