AJAX html won't refresh after data update

[Bart Van der Donck]

[...]
Microsoft is especially well-known to be backwards-compatible (no matter
how misguided that approach is at times).

On the contrary. Microsoft has a constant need to boost up their
sales, and they repeatedly announce not to support earlier products
anymore. NT, MS Access, Web Components, etc. Any experienced Microsoft
developer will tell you the same.

The statement in the MSDN Library (which is not a statement from Microsoft
but a statement of the MSDN Library editor(s)) is one that falls in the
category "insufficient" or even "factually incorrect"

I find the cited text very well formulated. Read it again - IMO the
author chooses his words very carefully. It's a mistery to me how you
would ever motivate your claim; which "fact" would be "incorrect" ?

| Microsoft Internet Explorer caches the results of HTTP GET

Have you not just confirmed that cache control headers have an effect?
That is not just random chance.

These headers don't deserve a status of "can be relied upon".

That idea is BAD because it fills the browser cache with garbage, and so
eventually slows down access to other content. Unnecessarily.

Wow. Didn't expect my little post to cause such 'discussion'.

I tend to go with the easiest solution that I know works and the unique
querystring method is that to me. Leaves me more time to tackle the more
complex parts of the project.

Anyway, I've serious doubts that the browser will have problems with (or
serious delays in) clearing any 'garbage' out of its cache. No more so
than normal lengthy browsing would fill it anyway.

Actually, Thomas, as you're asking others for proof; have I missed the
post where you prove the "eventually slows down access to other content"
statement?

You have not; I did not care to include it because that is self-evident if
you know how caches work.
