Varnish : how to add an exception for dynamic pages with cookies

[Josh]

It depends what you use the cookies for.  If they interact with code
to personalize the page then you can't cache them, but if they're
analytics cookies (for example) you can strip them out individually.
Here's the relevant line from my vcl:

set req.http.Cookie = regsuball(req.http.Cookie,
"(^|;\s*)(mbox|s_cc|s_cc|s_sq|s_vi)=[^;]+;?", "");

That pulls all the analytics cookies out from the back end request.
That's a better idea than just nuking the cookies, on the chance that
your code really is looking for one.  The server doesn't care about
any of those cookies, it's on page javascript elements that use them.
