Hey, I have four containers in Openstack Swift. One of the containers called "Cont1", and I am using the web browser to upload and download objects to/from Cont1. I need to add a script that runs each time someone downloads an object from the container Cont1. Let's say I want Swift to execute a small script every time someone clicks on the Download button. Wondering if that possible? Where I should add the code. I cloned Swift Stein git on my local machine but not sure where to add my script. Take a look at the attached image, to the very right there is a download button for object1. So when someone clicks on that button, I want to execute a small script, then after executing the script, Swift will start to download object1. https://imgur.com/cCZIJqR Note: I need to add functionality to Swift, so when someone requests an object download, swift will take an action based on the container name. Best Regards. Anmar Salih
