Note: this post applies to CloudBerry Explorer 2.4 and later.
As always we are trying to stay on top of the new functionality offered by Amazon S3 to offer the most compelling Amazon S3 and CloudFront client on Windows platform.
Content Invalidation allows you to remove an object from CloudFront edge locations prior to the expiration time set on that object. Invalidation is designed for unexpected cases where you need to remove an object from an edge location. For instance, you might use invalidation to fix an encoding error on a video you uploaded with a long expiration period, or update the css file for your website if it changes unexpectedly.
The newer version of CloudBerry S3 Explorer automates CloudFront object invalidation. Just go to your distribution, select the objects you want to invalidate and choose CloudFront Invalidation from the context menu.
Note: while both CloudBerry Explorer freeware and PRO support CloudFront object invalidation you can only invalidate multiple objects using the PRO version. With freeware you will have to invalidate objects one by one.
As always we would be happy to hear your feedback and you are welcome to post a comment.

Honestly, I would pay 99$ for pro version if it had a feature that allowed you to identify snyncable source and destination and then automatically expire destination assets on cloudfront... ;-)
Any idea what should be the procedure for updating an item (for example, replacing an image with a newer version?)
Do I upload the new version to S3, set the headers then invalidate it?
Or invalidate first then upload a new version?
Hi,
if you need to update your content quickly and don't want to wait until it expires according to the headers you should upload the newer content on S3 and then run invalidate command. Hope this will help

New version doesn't let my invalidate objects. The option is grayed out...
There is an issue that if you open CloudBerry Explorer where source tab displays the bucket contents, the CloudFront Invalidation context menu item becomes disabled. The workaround is to go up to the root and then go down to the bucket again.
We will make a patch soon.
The issue is fixed now. You can download the newer version here
Thanks for bringing that up!

How can content be invalidated when you're using origin pull? Nothing shows up in Cloudberry to invalidate...
I will pay for this app if there is a way to invalidate content on edge servers when there is no S3 bucket (i.e. we're using origin pull). Thanks!!
Another stumped developer looking for a hint on how to invalidate content using a Custom Origin server...
Seriously, there *must* be some way to do this (aside from versioning). If I can't invalidate an image file when it changes on my origin pull server then Cloudfront is pretty much useless to me.
Thank you for your comment. There is indeed the way to invalidate the content coming from non-S3 origins. We are going to support that in the future release.
@andy Invalidation for custom origin servers is the key feature I need before purchasing Cloudberry. Do you have an estimate when this feature will ship?
Hey guys, we have just released the version of CloudBerry Explorer PRO with an option to Invalidate Non-S3 Origin Distributions. Go to CloudFront Manager, select non-S3 distribution and click Invalidate button on the toolbar to get started. Then type the file names to the text box.
If I understand correctly, my method is ineffiecent?
So far, my method was:
-I first invalidate an image.
-Then I delete it
-Then I upload the updated image.
I have nothing in my headers about expiring.
Am I doing this wrong?
Object invalidation is an expensive and not recommended way to update the contents on the edge locations. You should use it only when absolutely necessary. In all other cases cache-control and expires headers is a preferred way to manage content expiration.
OK, thanks. Sorry if this is a dumb question: How do you control the cache?
The problem is that I often have to do tests for clients, so updating should be really quick, I cannot permit waiting for hours to see a change.
Rudolf,
we have two blog posts on content expiration headers. Please check out Two ways to configure content expiration with CloudBerry Explorer and
How to set custom http headers for Amazon S3 objects with CloudBerry Explorer. Let us know if it helps
Thanks

Excellent information, Andy. Thank you!
If i invalidate a folder, will invalidate all the subfolder and all the files inside each subfolder?
