Is there a way to refresh a particular portion of a web page without using frames or iframe?
thanks

No.
Ok, sort of. But it's ugly.
You can post your request to an invisible iframe and use the response to execute DHTML that manipulates the DOM of the main page. That way, you can change only a portion of the main page without having to redraw the whole thing as a result of the post.
It works, and I've used this technique on a few projects, but I'd only recommend this apporach when it is an absolute necessity.

Thanks Bear! I use the same kind of solution already. But that was lot of application logic in JavaScript and I wanted to avoid this.

I said it wasn't pretty!
Aside from DOM manipulation I think you're pretty much stuck with an iframe to create logical "sub-pages".
