Breadcrumb overrides

Advanced banning: Set your own banning rules for different hack attack codes. Even create your own ban pages (e.g. to mimic law enforcement bans for spammers).

Code overrides: Implement modifications to the Composr code without directly editing the original code by creating _custom files. This makes upgrading much easier. Also supports contentious_overrides hooks and the override_api for more advanced overriding.

Many different hook types allowing for modifying or extending Composr without modifying or overriding the code.

• 32-bit PHP build: Files larger than 2GB are not supported.
• 64-bit PHP build: Files larger than 2GB are supported, but the file size will not be displayed.

• Protection from hackers: Uploaded files are stored with obscured filenames, preventing direct access and bypassing of the download system. Additionally, an anti-leech feature (when enabled) prevents direct download links from being shared on other websites (this is done by requiring a session ID which is validated against the person / device accessing it and only provided when Composr presents the download links to you on the site).
• Basic security: Composr will not let anyone upload dangerous scripts (such as PHP files) which can be executed.
• Rootkit detection: The rootkit detection tool under yourbaseurl/rootkit_detection.php can help scan files for shell scripts and backdoors. Composr's Health Check can also do this regularly. Note this only offers very basic detection and will not work for obfuscated backdoors (you should use antivirus to scan for those).

• Create a new container gallery (e.g., with codename "downloads").
• Change the "Create download galleries under" configuration option to your new gallery's codename.
• Use Commandr to move existing galleries to the new location.

• Uploading via web form (when adding a download in the Content Management Zone): This is the simplest method, where you attach the file directly when defining the download details. However, it's not suitable for large files and can be affected by unreliable internet connections.
• Uploading and referencing the URL: You can manually upload the file using FTP/SFTP/SCP and then provide the URL to the file in the 'Add download' form. While this is better for large files, it requires additional

• Batch adding from an FTP server: This allows staff to add multiple downloads from an FTP server in one go using FTP URLs. It's efficient for bulk uploads but requires separate addition of descriptions.
• Batch adding from a directory: Similar to the FTP method, staff can add downloads from a web server directory accessible by URL.
• File/media library (filedump): Webmasters can use any of the above methods to upload a file to uploads/filedump and then reference it in a download. This is especially handy if you are going to reference the file more than once on your site.
