Question What is the purpose of "confirmed" and "non-confirmed" sessions?
Answer Composr distinguishes between confirmed and non-confirmed sessions for added security:
  • Confirmed: When you actively log in with your credentials.
  • Non-confirmed: When you return to the site and are automatically logged in via cookies.

You can configure zones to require confirmed sessions, preventing access from cookie-based logins alone. The Admin Zone uses this by default.
Question How can I enhance the security of my Composr installation on shared hosting?
Answer Shared hosting environments can be inherently less secure. Here are some tips:
  • Choose a Secure Host: Opt for hosts that offer suEXEC and open_basedir for better account isolation.
  • Test Security: Verify the host's security measures with the provided filesystem_browser.php script.
  • Restrict _config.php: Remove world-writable permissions from _config.php after installation.
Question How does Composr protect against Cross-Site Scripting (XSS) attacks?
Answer Composr utilizes multiple layers of defense against XSS attacks:
  • HTML Filtering: Configurable levels of filtering prevent malicious script injection.
  • Content Security Policy (CSP): Restricts the sources from which scripts and other resources can be loaded.
  • Input Sanitization: Data is sanitized before being processed to prevent malicious code execution.
  • Output Encoding: Data displayed to users is properly encoded to prevent interpretation as active code.
Question What are the different types of security alerts in Composr?
Answer Composr has a variety of hack-attack codenames that trigger security alerts and logging. Some common examples include:
  • DODGY_GET_HACK: Suspicious URLs with potentially harmful characters.
  • EVIL_POSTED_FORM_HACK: Possible CSRF attempts via malicious form submissions.
  • SCRIPT_UPLOAD_HACK: Attempts to upload PHP scripts, potentially malicious.
  • DOWNLOAD_PRIVATE_URL_HACK/TRY_TO_DOWNLOAD_SCRIPT: Attempts to download sensitive files.
  • BRUTEFORCE_LOGIN_HACK: Repeated failed login attempts.
  • SQL_INJECTION_HACK: Attempts to exploit SQL queries for data extraction.

You can customize alert handling for each type in data_custom/xml_config/advanced_banning.xml (Admin Zone > Security > Configure advanced banning).
Question What are some tips for secure website maintenance?

Question Why are my searches slow, and how can I improve search speed?
Answer Slow searches can occur when dealing with large amounts of content. Here are some workarounds and solutions:
  • MySQL timeout setting: For MySQL 5.7+, set a query timeout to prevent searches from locking up your database. Composr automatically sets this, but you can configure it manually if needed.
  • Use InnoDB tables: Switching to InnoDB tables in MySQL can prevent slow queries from affecting other users on your website. Note that InnoDB is not officially supported by Composr yet.
  • Enable the fast custom index: As mentioned earlier, the fast custom index is optimized for handling large datasets and filtered searches, potentially leading to significant speed improvements.
Question How does the search engine handle different languages?
Answer Composr's fast custom index supports multiple languages. Content is indexed based on its translated version, ensuring that you get relevant results even when searching in a different language.
Question What are quoted phrases and how do they work?
Answer Quoted phrases allow you to search for an exact sequence of words. For example, searching for "red apple" will only return results containing that exact phrase. Keep in mind that enabling quoted phrases can increase disk space usage.
Question How do stop words affect search results?
Answer Stop words are common words (like "the", "a", "is") that are ignored by the search engine because they add noise and don't contribute to the meaning of the search query. You can customize the list of stop words for the fast custom index. See the search tutorial for more information.

Question How can I ensure my website complies with email marketing laws?
Answer Email marketing laws like CAN-SPAM protect recipients' rights to unsubscribe. Your website must include a clear 'List-Unsubscribe' header in every email, offer an easy unsubscribe process, and respect unsubscribe requests promptly. Composr provides built-in mechanisms, including an unsubscribe endpoint and support for the List-Unsubscribe header, to facilitate compliance.
Question What are my responsibilities regarding user privacy?
Answer You must have a comprehensive privacy policy that details the personal data you collect, its usage, and if it's shared with third parties. Laws like GDPR have strict requirements, including logging data access, data purging, and security measures. California law mandates specific elements in your policy, like handling "Do Not Track" requests and a clear process for communicating changes.

Composr has an automatic Privacy Policy generator block to help you get started. This is used by default.
Question How can I create effective website rules?
Answer A well-defined rules page is crucial for setting expectations for user behavior and outlining consequences for violations. It should cover a range of offenses with appropriate punishments, reference relevant laws, and assign legal responsibility to users. Composr provides default rules pages that can be customized, and this page is displayed to users upon joining the site.
Question What are the key legal considerations for running a website?
Answer Several legal aspects need careful attention when operating a website, especially for large or corporate sites. These include establishing clear rules and terms of service, adhering to privacy laws like GDPR and California's regulations, managing personal data responsibly, complying with email marketing regulations like CAN-SPAM, ensuring website accessibility, addressing eCommerce regulations, and understanding liability for content and user actions.
Question How do data-tpl and data-view behaviors work in Composr's JavaScript?
Answer Composr uses data-tpl and data-view behaviors for associating HTML templates and JavaScript views, respectively. This facilitates clean separation of presentation and logic:
  • data-tpl: Used with the $cms.behaviors.initializeTemplates function and PARAMS_JSON tempcode directive to bind JavaScript logic to HTML templates.
  • data-view: Used with the $cms.behaviors.initializeViews function to associate JavaScript view classes (inheriting from $cms.View) with specific HTML elements.
Question What are the advantages of using Composr's JavaScript libraries?
Answer Composr's JavaScript libraries like $cms, $util, and $dom offer several advantages:
  • Organization: They provide a structured way to access Composr-specific functionalities, avoiding global namespace pollution.
  • Abstraction: They encapsulate common tasks, simplifying DOM manipulation, form handling, and interaction with Composr's UI.
  • Consistency: They offer a consistent API across different parts of Composr.
Question How does Composr implement the Model-View-Controller (MVC) pattern?
Answer
  • Model/API: The sources directory primarily houses scripts forming the Model/API, handling data logic and business rules.
  • View: Templates in themes/default/templates represent the View, responsible for presenting data to the user. Comcode pages can also be considered part of the View.
  • Controller: Entry scripts like index.php and site/dload.php act as front controllers, directing requests. Modules and blocks, residing in */pages/modules and sources/[mini]blocks, respectively, serve as controllers, managing user interactions and determining which View to render.
Question Can I translate my content into multiple languages?
Answer Yes, Composr supports multi-language content. You can enable this feature by:
  • Installing multiple language packs: Make sure you have at least two language packs installed.
  • Enabling the Conversr multi-language option: Go to Admin Zone > Setup > Configuration > Site options > Internationalisation.
  • Running a Commandr command: Execute the necessary command to set up the database structure for multi-language content (unless you already enabled Support content translations when installing).
Once enabled, you can translate your content into different languages and allow visitors to choose their preferred language.
Question My language uses gendered descriptors. How can I handle this in Composr?
Answer Composr offers solutions for languages with gendered descriptors:
  • Template editing: You can modify templates to use different language strings based on user gender. This involves adding Tempcode logic to dynamically select the appropriate string.
  • Custom Profile Fields: Create a Custom Profile Field for "Gender" and use it to conditionally display gendered language strings in templates.
These methods allow for flexible handling of gendered language variations.
Question What are language strings, and how are they used?
Answer Language strings are phrases or pieces of text used throughout Composr. They're identified by unique codenames, like WELCOME_MESSAGE. These strings are stored in .ini language files and used to display text in the user interface.

By translating language strings, you change the text displayed on your website without modifying the underlying code.
