[Help] DNS/Server Redirection

[Oddysey]

I've also had caching issue in the past, which lead to some research....

What I found is that there is a rather strange header that exerts some control over caching, it's called Vary. By entirely eliminating that one, a goodly portion of my issues were resolved.

Code:

In = TRUE
Out = FALSE
Key = "Vary: blank it out [IN]}"
Match = "*"

I also deal with the Cache Control header, which is often used haphazardly by sites of less-than-stellar programming capabilities....

Code:

In = TRUE
Out = TRUE
Key = "Cache-Control: always cache public (in)"
Match = "*"
Replace = "public, max-age=3600, no-transform"

That forces everything to be public, which means that the browser can deal with it, the Expire timing is pretty generous, and that sites can't 'hide' behind transformed URLs - where it truly came from is what I see.

On non-Netscape browsers, I have found Pragma: no-cache effectively useless. That doesn't mean it should be ignored by one and all, that means only that I realize no benefit from it on my IE only system.

HTH
