Caching #27

Caching using Memcached

This pull request adds support for caching HTTP requests, enabling efficient redirection of users to the original URL after caching and fewer calls to the database. It optimizes performance by storing frequently accessed short URLs in memcached for quick access.

Here's a simple micro-benchmark using UNIX time command:

Without caching

[hamza@archlinux shawty]$ time curl -i http://localhost:1234/s/996e1f71
HTTP/1.1 302 Found
Content-Type: text/html; charset=utf-8

real    0m0.968s # 0.968 seconds
user    0m0.004s
sys     0m0.004s

With caching enabled

[hamza@archlinux shawty]$ time curl -i http://localhost:1234/s/996e1f71
