The short answer is: No, you can't reproject it 'on-the-fly' either at the server or client. In my opinion, your best choice is to adopt the web-mercator alternate sphere projection. The next-best solution is to recreate the cache in the ...

Almost all basemaps you can access freely on the internet is in this projection. If you have all the original data, you can publish your own image service in perhaps any projection you want. But for cached image service, it's ...

This is an Old Question, but ESRI has finally cleared up the matters via a blog post in Feb 2014.

We do not plan to add these ...
