Handle-with-cache.c

When building a high-performance web server in C, the bottleneck is rarely the CPU—it’s the disk I/O. Every time a client requests a file, the server must navigate the filesystem, read the data, and pipe it to a socket. To solve this, we use .

: If found, the server serves the data directly from RAM. This is orders of magnitude faster than a disk read. handle-with-cache.c

A minimal cache entry struct:

The module handle-with-cache.c exemplifies a classic design pattern: the . A "handle" is an opaque pointer or identifier to a resource, and the cache stores recently accessed handles to avoid redundant initialization or I/O operations. When building a high-performance web server in C,

pthread_rwlock_t global_lock; // Readers-writer lock for cache metadata the server must navigate the filesystem
