Luit / shortener.vcl
Created December 1, 2011 11:03
A very ugly first version of a URL shortening service written in VCL inline C. There's a whole lot still to be done, but this thing works quite well already.
C{
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <hiredis/hiredis.h>
}C
sub vcl_recv {
if (req.http.host ~ "(?i)^a.luit.it$") {
if (req.url ~ "(?i)^/l/.*[A-Za-z0-9\-_]{4,}\+?$") {

A simple patch to fix libvmod-redis from completely halting to function after redis-server closes the connection

A much better version of a URL shortening service in VCL. It now uses libvmod-redis and works similar to the ugly Inline C VCL.
import redis;
sub vcl_recv {
if (req.url ~ "^/[lL]/[A-Za-z0-9\-_]{4,32}=?=?$") {
set req.http.New-Location = redis.call(regsub(req.url, "^/[lL]/([A-Za-z0-9\-_]{2})([A-Za-z0-9\-_]{2,30}=?=?)$", "HGET short:\1 \2"));
if (req.http.New-Location) {
error 666;
}
error 404 "Not Found";
}

A variation on the libvmod-redis based URL shortener, now doing a curveball to make the redirect cacheable.
import redis;
backend default {
.host = "127.0.0.1";
.port = "8080";
}
backend self {
.host = "127.0.0.1";
.port = "80";
