The main objective of this project is to specialize in one task: efficiently managing static web directories. Many current solutions are either excessively intricate with unnecessary features like CGI support and dependence on external libraries or they lack critical elements such as TLS, virtual hosting, or partial content handling. Quark intends to find a middle ground by concentrating solely on serving static content while still offering advanced functionalities typically seen in more elaborate systems, all with a focus on security through techniques like chroot, privilege escalation, and rigorous parsing without using dynamic memory. We believe that most of the web can function effectively without dynamic elements, contending that the rising complexity of server-side applications is a key factor in diminishing web efficiency. Today’s approach often involves handling everything on the server side—such as parsing requests, modifying files and databases, and producing HTML—frequently employing unsuitable languages like PHP or JavaScript, which can introduce significant security risks and inefficiencies. By streamlining these operations, we aspire to foster a web environment that is both simpler and more secure, ultimately benefiting users and developers alike. This focus on static content not only enhances performance but also reduces the attack surface for potential vulnerabilities.
