varnish memang lebih mudah diterapkan dimana2 coz ga make virtualhost misah beda dengan nginx jadi lebih mudah di aplikasikan ke beberapa tipe control panel

Ini versi yang udah fix.. mirip dengan script unixy tetapi tidak ada masalah dalam hal upload file..

Code: 
#This is a basic VCL configuration file for varnish.  See the vcl(7)
#man page for details on VCL syntax and semantics.
#
#Default backend definition.  Set this to point to your content
#server.
#
backend default {
  .host = "_diisi dengan ip_";
  .port = "_diisi port backend_";
}

#Below is a commented-out copy of the default VCL logic.  If you
#redefine any of these subroutines, the built-in logic will be
#appended to your code.

        /* Non-RFC2616 or CONNECT which is weird. */
        return (pipe);
    }
    if (req.request != "GET" && req.request != "HEAD") {
        /* We only deal with GET and HEAD by default */
        return (pass);
    }
    if (req.http.Authorization || req.http.Cookie) {
        /* Not cacheable by default */
        return (pass);

        set req.http.x-pipe = "1";

# These status codes should always pass through and never cache.

Hasil headernya script diatas.

Bug nya masih belum nemu lagi.. tapi upload file 3 MB udah no problem.. :) wordpress, joomla, dan cms lainnya udah jalan normal.. tidak ada kendala.. entah untuk masalah looping waktu erase thread varnishnya.. masih kejadian atau tidak..

coba aja default.vcl nya pakai ini isinya

backend default {
.host = "_diisi dengan ip_";
.port = "_diisi port backend_";
}

disave.. error apa ngga. kalau error ya mungkin tidak cocok vcl nya.. soalnya belum pernah coba di vbulletin
