In the last week, you may have noticed that when you type in zohowriter.com it goes to writer.zoho.com. This is a change we are making to all Zoho services. The old URLs will continue to work, so your bookmarks, embedding etc. are all fine, because they are all redirected to the new URLs.
Why did we make this change? It turns out that both IE7 and Firefox 2 now don’t automatically log you in to https://www.zoho.com/docs/sheet.html?, if you are already logged in to zohowriter.com. Due to new security changes in the latest browsers, services have to be on the same domain. With this change, single sign-on should work smoothly in the new browsers now.
