Hi

What are the correct cache headers to set if I need to tell varnish
not to cache a file.

Right now I use :

Pragma: no-cache
Cache-Control: s-maxage=0, max-age=0, must-revalidate, no-cache

But sometimes I get some other users cached file, and it seems to be
when I try to get a file in the exact same moment as som eother user.

In vcl i have the following code to allow caching af some of the
files even though a user is logged in.

# force lookup even when cookies are present
if (req.request == "GET" && req.http.cookie) {
lookup;
}

And when i request the file I get the following in varnishlog

15 VCL_call c recv
15 VCL_return c lookup
15 VCL_call c miss
15 VCL_return c fetch

16 RxHeader b Pragma: no-cache
16 RxHeader b Cache-Control: s-maxage=0, max-age=0, must-
revalidate, no-cache
16 RxHeader b Expires: Fri, 05 Jan 2007 08:57:03 GMT
16 RxHeader b Content-Length: 1555
16 RxHeader b Connection: close
16 RxHeader b Content-Type: text/javascript
15 TTL c 277100755 RFC 0 1168592154 1168592223
1167987423 0 0
15 VCL_call c fetch
15 VCL_return c insert

Could it be the insert that is made by varnish that is the problem ?
