Fully Ajax enabled Sharepoint Site

Guys,

please find some of the requirements which was submitted for us from a client as below with related to a SharePoint site which we were working.

1. There will be many static pages in the site
   1. HR.aspx (Static content place holder with rich html texts)
   2. Finance.aspx (Static content place holder with rich html texts)
   3. Sports.aspx (Static content place holder with rich html texts)
2. There should be only one Master page with a Quick Launch and Global Navigation.
3. The entire site should behave with fully Ajax enabled.
   • For ex:
     • When the user clicks a link in the Quick launch only the contents in content placeholder (Body) should be updated according to the link that the user clicks. (For ex: when the user clicks a HR Quick Launch link, the contents related to HR should be loaded from the HR static page).
     • When the user clicks on any links in the global navigation, entire page shouldn’t get loaded. Only the contents should be loaded.

if anyone did something similar to above please share your experience. As well as any suggestions, inputs greatly appreciated.

thanks in advance,

Ammar
