Advanced Task Manager: Gadget for Administration of Awaiting Review Tasks in Episerver

Currently, the User notification and Tasks (Awaiting Review) are disconnected and provide very basic information to the editors.

Tasks pane

User notification

The idea behind this project is two-fold. The first purpose is to build a more versatile Content Approval Sequence (Awaiting Review) task management gadget to extend the information available to the editors. The second purpose is to combine user notifications with tasks and empower Content Approvers to act on their tasks within a single interface.

SeoBoost: Internationalization (Absolute Canonical, Alternate Links & Breadcrumbs) for Episerver

The Episerver Html.AlternateLinks() &Html.CanonicalLink()  HTML helpers are very useful for developers to implement Hreflang & Canonical Tags with minimal effort but they always render relative Url(s).

Google support both relative and absolute URLs but absolute URLs are preferred: https://support.google.com/webmasters/answer/139066?hl=en&rd=1

Editor Access to Episerver Categories Admin Functionality


EPiServer separates the functionality for website editors and site administrators by using two distinct user interfaces (Edit & Admin interface).
Edit mode offers granular control by allowing you to set access rights for content.

The requirement is to provide editor access to a particular admin functionality i.e Categories, without providing full access to the user to the admin interface.

Invalidate the Site or Page Cache In EPiServer


Recently I was asked for a code snippet to manually invalidate site and individual page cache in EPiServer.

My first impression was why you want to go out of the way to manually invalidate site or a page cache when EPiServer automatically takes cares of it in a brilliant way?. It's not something you do in your daily EPiServer development routine, and being a big believer of "No such thing as a stupid question", it got me curious as I had some idea about doing this in theory but never actually get a chance to write a code to invalidate site or page cache.

The idea was to stress test load balancing environment where EPiserver event providers are doing the cache invalidation job but to disrupt their job through an invalidation cache web service. Later create a proof of concept in load balancing environment where EPiserver events providers for invalidating cache are disabled and on published event in CMS, a code gets triggers manually invalidation cache on site or page.

Bulk Upload/copy a Folder Structure and Files to Amazon S3 Bucket Using Windows Powershell

There are two ways to solve this problem:

Solution 1 - Write your own recursive function that iterate throughout all of your file and folder in your specified folder structure.
Solution 2 - Use a simple tool called "AWS Command Line Interface," provided by Amazon.

Lets now discuss both of these solutions in more  detail:

Solution 1.

In my previous post there is a perfect example of how you can write your own Recursive Function to List All Files in Folders and Sub-folders using Windows PowerShell. You can use the code as a base concept and create a functional code for uploading the folder structure to Amazon S3 bucket.

Quick tip here. According to AWS documentation "Amazon S3 has a flat structure with no hierarchy like you would see in a typical file system. However, for the sake of organizational simplicity, the Amazon S3 console supports the folder concept as a means of grouping objects. Amazon S3 does this by using key name prefixes for objects."

So you don't have to create folder in AWS S3 bucket before uploading the files. All you need to do is specify path to file e.g photos/abc.png and AWS will automatically create folder against the file abc.png

The downside of this approach is that it is a very slow process. For my folder (containing 2 155 Files, 87 Folders total size 32,8 MB), it took 41 minutes to upload everything on my AWS S3 bucket.

Solution 2.

Before we go through this approach we need to know, "What Is the AWS Command Line Interface?"

According to AWS CLI documentation "The AWS Command Line Interface is a unified tool to manage your AWS services. With just one tool to download and configure, you can control multiple AWS services from the command line and automate them through scripts."

In this Tutorial we will use AWS CLI tools (recommend approach).

Before we go further you need to keep in mind few things

- We will be using Microsoft Windows 7 or above.
- Make sure you download and install  AWS CLI tools in your Windows environment.

Here is the documentation for the S3 API via CLI:
If you read through the documentation, here is how our statement should look
aws s3 cp /tmp/foo/ s3://bucket/ --recursive --exclude "*" --include "*.jpg"

If you try do everything according to the documentation you will end up with the problem of setting up Environment variables (that's what happened to me at least). You need environment variables so setup AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY and AWS_DEFAULT_REGION

Tip: The way its describe to set Environment Variables in AWS documentation is for example
and this approach didn't work . So i end up using the different approach to set Environment Variables
[Environment]::SetEnvironmentVariable("AWS_ACCESS_KEY_ID","AK0BJUTDXP2PPTT ")

Final code
$folder = "c:\MyDirectory\"
$bucket = "AWS-BUCKET"
$accessKey = "AWS-ACCESS-KEY"
$secretKey = "AWS-SECRET-KEY"
$version = "1.3"


aws s3 cp $folder s3://$bucket/$version/ --recursive

Batch Rename All Files in a Folder to Lowercase in MS Windows

If you are not interested in external programs to renames all files in a folder to lowercase, there is a simple command for you.

- Open Command Prompt (cmd.exe) in Windows
- Go to the directory and run the following command

for /f "Tokens=*" %f in ('dir /l/b/a-d') do (rename "%f" "%f")

Note: This is not a recursive function, it will rename files to lowercase only on the directory where you will run the command.
