Digital marketers of today might want to work with dynamic product ads on platforms like Google and Facebook. This requires a machine readable product catalog file. To showcase how to make that data available, I created a tool for EPiServer Commerce, which generates and provides such a file.

When EPiServer runs in a load-balanced environment, the servers rely on exchanging event messages. EPiServer supplies four event providers. This post is about implementing a new event provider, using Redis as a broker for remote event messages.

I have heard a lot about Bitcoins and other cryptocurrencies. About what they are, what they can do and how much they will revolutionize payments and money transfers. So, as an experiment I decided to create an EPiServer Commerce plugin to accept payments in cryptocurrencies.

How can an AJAX service serve texts (error messages, label texts, product descriptions) or images from a multilingual EPiServer site? How to make sure that the server returns content in the correct language?

Read about a way to generically handle exceptions so they show a friendly error message to visitors, and a detailed stack trace to certain user groups.

When developing websites, sometimes adding extra attributes to certain HTML tags is needed. This is about how to do that dynamically on EPiServer properties, extending the Display Templates.

Imagine that you are developing a web platform (maybe even a SaaS product) to support multiple customers. It could be built as a multi-tenancy application, that offers a basic subscription and a variety of optional add-ons. How could authorization of access to each add-on be easily implemented?

I once did a big migration of an old Subversion (SVN) repository to a new Git repository, migrating all of the version history. This post is about how to do that.

Whenever a webpage have links to pre-compiled frontend files, we as developers can make the web browsers, as well as proxy servers, cache (save) the files for a very long time. But what happens when you make changes to one of those files on the server? How can we do both extremely long caching and invalidate the cache at any time?

In all the projects I have worked on for various clients, we had to load, cache and make use of a user's profile data in the application. How to do that in a very efficient and scalable way, is something I care for a lot. Here are my thoughts and ideas about that topic.
