how to implement swf address navigation in struts 2

I want to implment swf address navigation in struts 2 like twitter and facebook navigation. I meant to say for each page user navigation header and footer and some common compone开发者_如何学Gonts across the websites will not be loaded for each user navigation. in some sites like twitter and facebook they have done with swf address implementation by concatinating '#' to current url for each user navigation with required pagename.so i want to implement same thing in struts 2. So how can i implement it.

I don't know what you mean by "swf" navigation; I only know swf as Flash, which neither Twitter nor Facebook use for navigation.

Why do you want a "#" in the URL? What do you think it does?

In any case, if what you're asking is really "How do I get only some parts of the UI to update during navigation", the answer is either Ajax, or iframes. (Personally, I think iframes are almost always wrong, especially with what modern JavaScript and CSS allow, but they have their uses.)

First of all I am not sure about the term SWF Address Navigation. Hash Bookmarking is a more common phrase for libraries that actually does this task.

This is a matter of client side programming and it has nothing to do with struts 2. There is a good jQuery plugin for that. It is called jQuery history plugin.

You can find lots of other libraries and the best choice depends on your application requirements.
