When I try to navigate to any page of the documentation, I get a BlobNotFound error:

Example: [http://cesiumjs.org/cesium/build/documentation/AnimationViewModel.html](http://cesiumjs.org/cesium/build/documentation/AnimationViewModel.html)

\<Error\>

Where are you getting your links from? Your URL casing is incorrect. Does the below work for you?

When Googling for "cesium js documentation," the first link is to:

> **[CesiumJS](https://cesium.com/cesiumjs/)**
>
> An open source JavaScript library for creating 3D globe applications

Some links seem to work, and others do not. Which links work also appears to change over time. For example, right now [http://cesiumjs.org/cesium/build/documentation/AssociativeArray.html](http://cesiumjs.org/cesium/build/documentation/AssociativeArray.html) does not work, but [http://cesiumjs.org/cesium/build/documentation/Appearance.html](http://cesiumjs.org/cesium/build/documentation/Appearance.html) does work.

It seems like going to the documentation page once on the "correct URL" makes subsequent requests work on the wrong-case URL.

For example, when I first go to:

> **[CesiumJS](https://cesium.com/cesiumjs/)**
>
> An open source JavaScript library for creating 3D globe applications

I get the error. But when I go to  
[http://cesiumjs.org/Cesium/Build/Documentation/Queue.html](http://cesiumjs.org/Cesium/Build/Documentation/Queue.html) (which works)  
and then go back to  
[http://cesiumjs.org/cesium/build/documentation/Queue.html](http://cesiumjs.org/cesium/build/documentation/Queue.html)  
it now works.

Okay, thanks. I’ll write up a bug to figure out why that’s happening and get it fixed.

FYI, we added a rewrite rule so that lowercase links work now. Thanks again for reporting this.
