Question Why is understanding XHTML important for website customization?
Answer XHTML (Extensible HyperText Markup Language) is the language used to structure web page content. It defines the various elements of a webpage, such as headings, paragraphs, images, and links.

Understanding XHTML is crucial for website customization because it allows you to:
  • Modify page layout: Change the arrangement and positioning of elements on a page.
  • Add new content: Insert additional text, images, or other multimedia elements.
  • Customize the appearance of existing elements: Change fonts, colors, sizes, and other visual styles.
  • Integrate interactive features: Embed JavaScript code for dynamic functionality.

Composr uses XHTML for its templates, allowing users to extensively customize the website's design and layout.
Question How does JavaScript enhance website interactivity?
Answer JavaScript is a programming language that runs in web browsers, allowing for dynamic and interactive elements on web pages. It enables features like:
  • Dynamic content updates: Modifying page content without requiring a full page reload.
  • User interface enhancements: Creating interactive elements like dropdown menus, image sliders, and form validation.
  • Animations and visual effects: Adding visual appeal and engaging user experiences.
  • Asynchronous communication: Fetching data from, or sending data to, servers in the background without disrupting user interaction.

Composr relies on JavaScript for its default theme and administrative features.
Question What is the difference between cookies and sessions?
Answer While both cookies and sessions are used for user identification and maintaining state, there are key differences:
  • Storage: Cookies are stored on the user's computer, while sessions are stored on the server.
  • Expiration: Session cookies expire when the browser is closed, while persistent cookies have a set expiration date. Sessions typically expire after a period of inactivity.
  • Data sensitivity: Sessions are generally used for more sensitive data, as the information is not stored on the user's computer and therefore less likely to be stolen by a hacker.

Composr uses both cookies and sessions. Session cookies are primarily used for user identification (such as anonymously matching a user to a session in the server database), while persistent cookies can be used for remembering login details if the user chooses.
Question What are cookies and how do they work?
Answer A cookie is a small piece of data that a website stores on a user's computer. It is sent from the user's web browser to the web server each time a page is viewed. Cookies are used for various purposes, including:
  • User identification: Cookies can be used to identify a specific user, even if they are not logged in. This allows websites to remember user preferences, shopping cart contents, and other information.
  • Tracking user behavior: Cookies can be used to track user behavior on a website, such as the pages they visit and the links they click. This information can be used to improve the website's design and content.
  • Advertising: Cookies can be used to deliver targeted advertising to users based on their browsing history.

There are two main types of cookies:
  • Session cookies: These cookies are temporary and are deleted when the user closes their web browser. They are often used to store information about the user's current session, such as the items in their shopping cart.
  • Persistent cookies: These cookies are stored on the user's computer for a longer period. They can be used to remember user preferences, such as their login details or language settings.
Question What are the different media types supported for banners?
Answer The Composr banner system supports various media types:
  • Images: Uploaded directly or via an image URL.
  • Text: Textual banners, including support for "hot text" that dynamically displays banners based on keyword matches within the content.
  • Frames: Banners embedded within frames using an iframe URL.
  • Direct Code: Raw HTML or PHP code can be used to integrate banners from third-party banner networks or create custom banner implementations.
Question What is a banner wave, and how is it different from a banner rotation?
Answer A banner wave displays all banners within a specific type as a single advertising block, similar to a list of sponsors. In contrast, a banner rotation randomly displays banners from a set based on factors like display likelihood.

You can add a banner wave using the main_banner_wave block and configure it to show a specific number of banners or all banners within a type.
Question What is a banner network, and how can I create one?
Answer A banner network is a system for exchanging banners between websites. You can create a banner network in Composr by associating banners with specific websites.

When a site joins your banner network, you provide them with an iframe code to display banners from your rotation. Composr uses a "hit balancing" system where sites in the network receive banner impressions based on the clicks they generate for other sites in the network.
Question Can I restrict who can see specific banners?
Answer Yes, by enabling the "Permissions" configuration option in the Admin Zone (Admin Zone > Setup > Configuration > Feature options > Banners), you can control which usergroups can see individual banners. This feature allows for banner targeting and prevents inappropriate banners from being shown to specific audiences, such as adult banners to minors.
Question What are the different types of banner deployment agreements?
Answer There are three types of banner deployment agreements:
  • Permanent: These banners are always displayed as long as there is available space.
  • Campaign: These banners have a limited number of impressions or clicks before they stop displaying. They can be associated with specific campaigns and can have their hits increased if needed.
  • Default: These banners are displayed only when there are no permanent or campaign banners available to show.
The system displays permanent and campaign banners with a 50:50 split.
Question What should I do if URL Schemes are not working properly?
Answer If URL Schemes, which rely on web server rewrites, are not functioning correctly, you can disable them using the http://yourbaseurl/config_editor.php script. Enable the option "Whether to block the URL Scheme (mod_rewrite)" to override the main configuration setting.
