Let’s say a user has a menu that has only a top level. This does not have to be a menu - anything in general that has the same code over and over again. Would it be beneficial to place all of this code in an Iframe that can be cached? If a menu is within an IFrame, I do not think it would work if it has drop down menus. I think the drop down menus would be cut off at the bottom of the IFrame. I do not think a z-index would help in this case.
Is there anyway you can cache part of a page instead of the entire page? I was reading an adobe article on coldfusion 9 and it was saying that coldfusion 9 is able to cache the processing for part of a page:
It would be nice if there was a way you could cache part of the page that gets sent to the user. I suppose this is what IFrames are for or is there another way?
