Introduction to the Application.cfc Object and Application Variables in ColdFusion 9

by John Farrar | July 2010 | Web Development

There is a huge difference between a web application and a dynamic web page. Web applications persist basic information, so we can create things such as shopping carts, user authentication (login and logout), and much more. HTML helps us to click through pages with links. In this two-part article series, we will learn how we can use web server memory to create engaging and interactive web applications by using variable scopes.

In this article by John Farrar, author of ColdFusion 9 Developer Tutorial, we will have a look at the following topics:

  • The life expectancy for various types of information. This affects the system memory and the place where different information is stored.

Security in Plone Sites

by Alex Clark | July 2010 | Open Source

While Plone is quite fortunate to be built on top of the very safe and secure Zope 2 application server, there is always more we can do to make sure our site is running as safely and securely as possible.

Because security is such a big topic, there are many areas where we can perform audits and make improvements such as operating system (OS), flesystem (FS), through the web (TTW), and so on.

Lastly, there are some miscellaneous tasks that fall under the security umbrella; we can take this opportunity to learn them.

So let's get to it.

In this article by Alex Clark, author of Plone 3.3 Site Administration you will learn:

  • Restricting TCP/IP access to localhost or LAN host
  • Managing IP addresses and ports effectively
  • Configuring the Zope 2 effective user dynamically
  • Installing Cassandra to audit through the web (TTW) security
  • Applying security and bug fixes to Plone
