Single web page site settings questions ... i.e. KeepAlive,

["Rose, John B" <jbrose@xxxxxxx>]

For a one page web site

The page will have a very large number of visitors in a short time.  There will be simple text updates on the page and users will check back frequently to see the updates.

Say 100k visitors each minute.

For instance an emergency/disaster information/status page.

1. Is there any reason to have KeepAlive set to "On" ? If so, suggested KeepAliveTimeout?

2. Any other suggested Apache configuration settings for such a web site?

3. Is there some way to cache the page in RAM?

4. What if there is one section on the page that will be updated very frequently in a server side include, jquery, php include, etc, somehow, and we do not want to cache that part, but cached the rest of the page?

Thanks for your time
