Bypass cache when add to cart ?

[Per Buer]

Hi,

Sure. Here is a hint.

Read through the the relevant parts of the Varnish Book or varnish-cache.org's
"Users Guide". What you're looking for is "passing" certain requests.
You'll control this in vcl_recv and the part that tests on the query string
will look something like this:

if (req.url ~ "\?.*foo=bar") {
    return(pass);
}

You might want to have a look at the cookie vmod, especially if you
struggle with regular expressions.

Per.
