We have released a new feature in Visual Website Optimizer which lets you host the JavaScript files on your own server. This was done because a lot of large corporations avoid including external JavaScript files from a third party. Even though our JavaScript is hosted on Amazon S3 and we have a fail-over strategy that guarantees zero downtime (even in case of our servers going down), some corporations feel much safer if they control the resources (JavaScript, CSS, etc.) used on their websites.

The latest feature allows you remove dependency on our server while the test is running. All the test settings, variation content and code needed to run the test will be stored on your server (as four separate JavaScript files). VWO server will only be used for logging hits and conversions (which is an asynchronous activity).

Hopefully, you like the freedom of hosting JavaScript files on your server! Let us know your comments and thoughts using the comment form below.

1. Does this mean that the implementation of the ‘cookie storage functionality’ of the browser inside the VWO, will also be hosted on our servers if we chose to host VWO ourselves?

   Thanks

2. @Juan: yes, everything (except logging) will be done on your servers.
