Question

I wanted to use this statement

<%@ OutputCache Duration="20" Location="Any" VaryByParam="none"%>

for our homepage.
(this works by the way)

But there are multiple domains pointing to the same site, like mydomain.fr and mydomain.ch.

Then, in the basepage i set the culture of the site to fr-FR if they typed mydomain.fr, de-CH when they typed mydomain.ch etc.

I was wondering, as both url’s would load the same page /default.aspx, is the page served the same for both users (so when .fr comes first, the .ch visitor sees the (cached) .fr page), or does the framework think and say: hey, mydomain.fr/default.aspx is not the same as mydomain.ch/default.aspx, even if it’s the same fysical page, so let’s NOT take the cached one and recreate (and cache) a new version?

I’ve read about varybyheader for the page output caching, but .fr vs .ch is not a header i think?

Answer 1

You could vary it by the HOST header, which would mean that each domain would have its own cache set.

The HOST header contains the hostname/domain name that the browser loaded; So, mydomain.fr or mydomain.ch, etc.
