Is there a way to disable asp.net caching on selected page. It would be nice if this can be done from the web.config.

<!-- In the page itself -->
<%@ OutputCache Location="None" %>
Or
// In the code-behind
Response.Cache.SetCacheability(HttpCacheability.NoCache)
Unfortunately, it has to be done within the page. There's no easy way to do it from web.config. For more information, check out:

Yes you can if you are willing to create your own config section: http://msdn.microsoft.com/en-us/library/2tw134k3.aspx
In your config section put something like,
<cachingConfig>
<path>/Navigation/Menu.aspx</path>
<path>/Target/Console.aspx</path>
<path>/Target/Charting/Chart.aspx</path>
</cachingConfig>
You could add more properties such as duration if you like.
Then, on the page_Init method of your pages, check this configuration section and call the following where appropriate:
Response.Cache.SetCacheability(HttpCacheability.NoCache)
Edit: Tip: Put the init code in a base class that your pages inherit, so that it is only one place.

Response.Cache.SetExpires(DateTime.UtcNow.AddMinutes(-1));
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetNoStore();
