You should include a complete URL when including website citations.
However, be aware that only some eBook readers will use such a link. Apple iBook (iPad and iPhone) does, and clicking a link will give you the opportunity to leave the eBook and jump into the Safari browser. But many eBooks don't offer browser support.
Hmmm, I just saw on Adobe TV that you could create a link with the hyperlinks panel and put the whole url, including the http:// in the url field of that panel and leave the wording unencumbered in the book itself. I was hoping to not have all those http:// s in the listing of websites in the acutal book.
I want to have it look like this www.blablabla.com
and not like this http://www.blablabla.com
Can someone tell me if this is indeed possible?
I created a listing "www.adobe.com" and used the Hyperlinks panel to give it the URL http://www.adobe.com.
I just tested and it works on Apple iBooks on an iPad.
That doesn't say though that it would work on other eBooks.
