Whilst setting up Optimizely 12 to work with RabbitMQ is rather straight forward, making it use ActiveMQ for transport instead requires a bit more configuration on our part. Here is a short article on how to set up Optimizely 12 to use MassTransit (EPiServer.Events.MassTransit) with ActiveMQ. For a short instruction on how to set up a local ActiveMQ server, please see Muthu Kumaran‘s article on …
I’ve updated the ActiveMQ tester application with topic support as it is required by the Optimizely on-prem event provider (EPiServer.Events.MassTransit). Otherwise, the usage is as before (see ActiveMQ connection tester application). Source code at GitHub.
While moving our client’s Optimizely 12 website to a new hosting provider we had to abandon our RabbitMQ installation in favour of a new ActiveMQ one, also supported by the on-prem event provider (EPiServer.Events.MassTransit). To make it easier setting this up I rewrote the old RabbitMQ connection tester application into a new one working with ActiveMQ. Source code and executable are available at GitHub. To …
My current client is moving their Optimizely 11 websites to a new hosting provider and we need an easy way to test the remote event replication system. I remember that there was an old console application for this back in the day, but when I found a copy of it I realized that it required .net 2.0 to function. I shamelessly disassembled the application and …
We set up Optimizely‘s new on-prem event provider (EPiServer.Events.MassTransit) for my current client’s Optimizely 12 website the other week. At current date it is still in beta until there are enough uses for there to be a production release. For the mass transit we set up RabbitMQ. For earlier Optimizely (Episerver) versions built on ASP.NET Framework there was a tool for testing the event replication …
As stated in the Optimizely Search & Navigation developer documentation on Sorting, “Sorting is supported for numerical types such as int, double, DateTime, and string”. This means that you will get an error from EPiServer.Find.SortingValidationHelper.ValidateSupportedType if you attempt to sort on an enum field. There are of course various solutions to this problem, but here is a rather simple one: turn the enum into a string …
I got a question on how to find the latest version of the Search & Navigation /epi-util/find.js script file after publishing the article Proxy for Optimizely Search & Navigation tracking script. It is really quite simple, if you look at how Optimiezely does things. The solution is to make use of the built-in IPathHelper (namespace EPiServer.Find.UI.Helpers). Optimizely’s default GetClientResourceBasePath implementation essentially makes a request to …
When using Optimizely Search & Navigation (previously Episerver Find) you will automatically get a reference to a client side Javascript injected into your markup. Occationally, you may want to proxy it via your Optimizely website’s backend, caching it or just make it appear as if it comes from your own domain. It may also be a way of avoiding false positives in regards to script …
In our work to automate export and import of the production database into our test environment we had to maintain a test node in the Episerver page tree. This ment that we had to export it before replacing the database, and then import it again. Please see Exporting Episerver content programmatically through an ApiController and Importing Episerver content programmatically through an ApiController for information about …
Importing the test node package that we exported earlier (see article Exporting Episerver content programmatically through an ApiController) would be the next step in our automated transfer of the production database to the testing environment. I extended our ApiController with an import endpoint for this purpose. Note that this code is never intended to be deployed to production. Importing is easier than exporting. The relevant …
As part of the automated transfer of the production database to the testing environment for my current client we found the need to maintain a node in the Episerver page tree that is used for testing. I extended our ApiController with an export endpoint for this purpose. Note that this code is never intended to be deployed to production. So the interesting part happens in …
Attempting to match timestamps and whatnot to correlate requests over various logs may be quite tedious. Adding a correlation ID to your website makes this easier and may save you quite a bit of time. This is what we did at my current client for all of their Episerver websites. I Implemented this together with my collegue Svante Seleborg. Passing a correlation ID through your …
Just a short note on an exception I got after upgrading the Episerver NuGet packages on a few of my client’s websites. All of them worked perfectly, except the one that gave me the following message: It is the package.config inside the Shell.zip that it’s looking for. It turns out that the package installation had removed a few lines from the configuration file.
Adding custom information along with the usual message and stacktrace in your exceptions may possibly make it easier to find out what’s happening in your Episerver website. Here is a bit of code showing how it may be done in a quite simple way. I created it some time back and it has since then been improved by my collegues Svante Seleborg and Martin Lindström. …
If you want to pass information between a PublishingContent handler and a PublishedContent handler (EPiServer.Core.IContentEvents) it is quite easy as the internal code provides you with a Dictionary property on the ContentEventArgs object. This may be useful if you need to maintain information about a property value through an entire publishing process. I.e. find out if the editor changed the value of the property. So, …
We use the JOS.ContentSerializer to provide JSON for React in a platform project at my current client (7 Episerver websites spread over 5 installations). For this we needed to provide the JOS.ContentSerializer with custom settings via the IContentSerializerSettings interface to use in our custom property handlers. However, we encountered some difficulties doing this and here is how we (temporarily) solved it. I will make the …
Some time ago we had a rather elusive bug on one of my client’s Episerver websites: occationally an item would disappear from a menu, even though no editor involvement had been noted for at least 6 months. My collegue Svante Seleborg found the rather interesting cause of the problem. Intersecting Episerver content We had a line of code intersecting two collections of pages, like this: …
I had to add a character limit to an XHtmlString property in Episerver on a publish event the other day, and knew I had get rid of the markup to get an accurate count. I was pleased to find that the good old TextIndexer was still in there to clean the HTML for me. Here is a short reminder on how to use it:
Sometimes you need a sitemap index file for easing access to multiple sitemaps. Here is a way of creating one using a custom generator for GETA SEO Sitemaps, described in Multiple custom sitemap.xml generators with GETA SEO Sitemaps for Episerver. The UseGeneratorFor method will expect the index file to be named sitemap.xml, so be sure to create one of those in your Episerver admin mode …
At my current client’s, we’re building a common platform code base supporting 5 Episerver multisite installations. These all have different needs when it comes to xml sitemaps. Here is an easy way of adding custom sitemap generation and have the GETA SEO Sitemap functionality use it. Overriding the generator factory The first thing we need to do is come up with a way of recognizing …
