This is possible because the module allows a certain degree of customization of the generated content: * Custom headers. Either local or stored remotely. * Custom footers. Either local or stored remotely. * Add you own CSS style rules. * Allow choosing to sort elements by name (default), modification time, or size; both ascending (default), or descending. -------------------------------------------------------------------------------- Update Information: Changes with nginx 1.26.3 05 Feb 2025 *) Security: insufficient check in virtual servers handling with TLSv1.3 SNI allowed to reuse SSL sessions in a different virtual server, to bypass client SSL certificates verification (CVE-2025-23419). *) Bugfix: in the ngx_http_mp4_module.
