PHP Summercamp Rovinj: HTTP Caching with Varnish - Workshop

27.8.2015
Conference: PHP Summer Camp 2015, Rovinj, Croatia
Title: HTTP caching with Varnish

For some scenarios, Varnish is the silver bullet to fix performance issues and go from slow site to lightning fast site. More often though, you will need to put some effort into your application to get good results. Ideally, you design your application to play well with caching from the outset. If you don't know what you are doing, Varnish can also be the bullet to shoot yourself in the foot.

DPC Amsterdam: CMF and Varnish

25.6.2015
I was in Amsterdam at DPC and did two workshops, one on the Symfony CMF and another on Http caching with Varnish. I also did a regular talk to introduce to Http caching. The Varnish workshop and talk I did together with David de Boer, who is co-authoring the FOSHttpCache and -Bundle with me.
Additionally, before the conference I went to Leeuwarden to present the CMF at a meetup of the PHP Friesland user group.

Varnish and HTTPS with Apache

20.3.2015
Today I wanted to run a website with HTTPS and Varnish. Varnish itself does not support SSL, and for good reasons. So the setup we need is HTTPS termination => Varnish => Webserver. So we need a software that can handle HTTPS and forward requests over HTTP to Varnish. A couple of options for HTTPS termination are HAProxy, Nginx, Squid or Apache. I went with Apache, as it was already installed on the server in question, thus reducing the complexity of the setup.

On Apache, you need to enable mod_proxy. The Apache SSL configuration looks like this:



#/etc/apache2/sites-available/example.com-ssl

<VirtualHost *:443>

    ServerName www.example.com



    ProxyPreserveHost On

Varnish is a server component that runs independent from your web server, making it useful whether your application is written in PHP,

Conference: Madison PHP Conference, Madison, WI
Title: HTTP Caching with Varnish
Links: Slides, joind.in

With the Varnish caching proxy, you can make slow websites blazingly fast. The basics are quite simple once you understand how the cache handling in HTTP works. For starters, we will look into HTTP and the Varnish configuration. The main course is going to be cache invalidation and the cache tagging strategy. For dessert, there will be an introduction to edge side includes (ESI) - all liberally sprinkled with examples from the FOSHttpCache library and some ideas from the FOSHttpCacheBundle for Symfony2.

Conference: phpDay Italy, 16-17.5.2014
Title: Content Management with Symfony2
Links: A few Slides, Tutorial Code, joind.in

The Content Management Framework (CMF) is a set of building blocks for content management. You can use just parts of it to add some content management to your Symfony2 project, or use the whole stack to build customized CMS applications for specific needs.

In this workshop, we do a hands-on tour through the CMF. We look at the existing functionality and implement simple features to get a feel for how things work.
