Regular Expression Engine Comparison Chart

Many different applications claim to support regular expressions. But what does that even mean?

Well there are lots of different regular expression engines, and they all have different feature sets and different time-space efficiencies.

The information here is just copied from: http://regular-expressions.mobi/refflavors.html

# filter by request host header
varnishlog -q 'ReqHeader ~ "Host: example.com"'

# filter by request url
varnishlog -q 'ReqURL ~ "^/some/path/"'

# filter by client ip (behind reverse proxy)
varnishlog -q 'ReqHeader ~ "X-Real-IP: .*123.123.123.123"'

# filter by request host header and show request url and referrer header

Simple cache busting with Nginx

You update your app.js or styles.css, but have a caching of 30 days and none of the clients will get the latest version? 😟

While the best would be to use a build mechanism to generate new filenames on the server, here is how to ensure clients get your last updates:

1. Change the name of the files in the HTML, for example styles.css to styles.123.css

2. Add this cache busting snippet in your nginx conf:

ssreekanth

#!/usr/bin/env bash
# -----------------------------------------------------------------------------
# @author  Sreekanth S
# -----------------------------------------------------------------------------
#

function binary_exists() {
    which ${1} &> /dev/null
}

# your nginx version might not have all directives included, test this configuration before using in production against your nginx:
# $ nginx -c /etc/nginx/nginx.conf -t

server {
        # public key, contains your public key and class 1 certificate, to create:
        # (example for startssl)
        # $ (cat example.com.pem & wget -O - https://www.startssl.com/certs/class1/sha2/pem/sub.class1.server.sha2.ca.pem) | tee -a /etc/nginx/ssl/domain.pem > /dev/null

The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

1. Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

git clone --bare git@github.com:usi-systems/easytrace.git

gen_ssl_cert

This script generates a self-signed SSL certificate which can be used for developing web applications on your local machine. The certificate will be generated using RSA-4096 and SHA512.

Installation

Copy these two files somewhere convenient; e.g. ~/bin.

Edit openssl.cnf if you have any particular requirements.
