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 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.

View

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.

View

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.

View

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 What are redirects and how can I use them for subsites?
Answer Redirects let you create custom URL paths that point to different zones and pages within your site.

Examples:
  • Sharing modules across zones: Create a redirect to make a module in one zone appear in another.
  • Creating shortcuts: Use a redirect to point a short URL to a longer, more complex URL.
  • Moving pages: Use a redirect to ensure old links still work after moving a page to a new location.

Go to Admin Zone > Structure > Redirects.

Question What are virtual roots and how do I use them?
Answer Virtual roots let you make a sub-category within a Composr module (e.g., downloads) appear as the top-level category. This is useful for creating separate "databases" of content for different subcommunities.

To create a virtual root:
  • Enable "Virtual root links" in the Admin Zone > Setup > Configuration > Feature options > Advanced.
  • Navigate to the desired category while logged in as staff.
  • Click the rightmost link in the breadcrumbs (it will be an anchor for virtual root creation).
  • Use the resulting URL in your menus to link to the "virtualized" category.

Question Can I have subsites and subcommunities within a single Composr installation?
Answer Yes, Composr offers various tools to create subsites and subcommunities within a single installation:
  • Zones: Create separate sections under different URLs with their own pages and content.
  • Redirects: Make modules appear in different zones without actually moving them.
  • Categories & Virtual Roots: Organize content like galleries, downloads, and catalogs into sub-trees that appear as separate entities.
  • Usergroups & Permissions: Group members into subcommunities and control their access to specific content.
  • Themes: Customize the look of different zones.

Question What is the difference between a central site and a satellite site in an M.S.N.?
Answer The central site hosts the shared forum, member database, and netlink system. It is the core of your M.S.N.

Satellite sites are the additional websites within your network. They connect to the central site for member information and forum access.

View

Question What are the advantages and disadvantages of using an M.S.N.?
Answer Advantages:
  • Full control: You have complete control over each site's settings and content.
  • Administrative separation: Managing staff and content for each site is more organized.
  • Special M.S.N. features: Composr provides specific features like the 'netlink' system for easy navigation between network sites.

Disadvantages:
  • Configuration and maintenance: Setting up and maintaining multiple sites can be more complex.

Question What is a multi-site network (M.S.N.) in Composr?
Answer An M.S.N. allows you to run multiple Composr websites (installations) that share a common forum and member database. It's ideal for website networks with shared communities but segmented content, staff, or branding. In essence, members who join one site automatically have accounts on all sites within the network.
