 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 ?
