Browser Compatibility

If you're running into compatibility issues, here's some diagnostic information that may help out.

• Javascript Disabled

  Both the eHub website and reader require Javascript to function. If this feature has been disabled in your browser settings, you'll be unable to use many features of this site.

• HTML5 Canvas Support

  The eHub HTML5 reader makes use of some of the latest browser technology. Unfortunately, older browsers sometimes lack this feature, which is necessary to the use our reader. If HTML5 canvas support is not detected, we'll automatically degrade to a feature-limited Flash-based reader, however user-experience will be impacted.

• Browser/Network support for HTTP Range requests Checking...

  To optimize content delivery, our reader requests only those pages within an ebook that you are currently viewing or are predicted to view in the near future. This requires both your browser and network to support HTTP Range headers. If support is not detected, our reader will gracefully degrade to a streaming delivery, but this may impact load times when opening our content, especially if jumping ahead by multiple pages at a time.

• Browser Robot/Spider

  We recommend you use a reasonably updated version of your browser. To see a list of supported browsers, please review our FAQ.

• Operating System Unknown

  So long as you are using a supported browser, you should be good to go. However, please note our technical support staff can only assist you with issues related to our list of supported operating systems found in our FAQ.

• Client IP Address 34.238.189.240

  This is the unique address of your computer on the Internet. This may be useful for our investigation should you need to call technical support. If this value differs from what you know to be your computer's IP address, you may be passing through a proxy.
