What is the difference between cache for web pages and cache for ajax calls?

This anwser suggest "send 'no-cache' HTTP headers back with your response from the server." to work around ajax calls caching issues in IE.

With my limited knowledge, I assumed such a type of setting "no-cache" referred to grabbing a new page from the browser.

Does no-caching in general just block a name value pair object from being sent to the server? - Which is the behavior I see when caching is enabled for an ajax call with the same previous name/values?

Yes, if a server sends the Cache-Control: no-cache header, it means that the browser must not use a cached copy of the page for future requests, i.e. it forces the browser to re-fetch the page every time.

There is no special cache for AJAX. It just happens that IE caches AJAX responses just like any other web page. Clearly, this leads to wrong results for multiple calls using the same URL.
