Can varnish be used on a e-commerce website where almost all pages are dynamic?

Hello, I'm working on a e-commerce site, and the content of it is almost fully dynamic.

Most user must login to purchase, and every login user in have a collection of personalized items displayed in every page. And every item's status is in real-time(whether it's in stock, and how many left).

So for now, we dynamically generate every webpage, and use a CDN to delivery all static files(images, css, js).

Then, can varnish be used in such situation where almost all things is dynamic? As I see Facebook is also using varnish, and I'm wondering how fb did it.

hi,

as nobody more experienced than me bothered to answer up to now, i might
just tell you some very basic things.

most dynamic pages only have a small part of it, that really is dynamic.
sometimes, that part can be loaded with ajax, so the first page to get
is cached. if this does not work, edge side includes might provide an
answer. that way you can assemble the dynamic pages on the server. check
the wiki for details.

good luck,
tobi

Yes. As someone already pointed out - mostly people use ESI for this. Or
Javascript.

That's a rather soft real time requirement. You can probably cache those
for at least a second or two or ten. Nobody will know and your database
will love it.
