the widget will show backend status and to see varnish logs, you can use varnishlog from console

Hi Marcello, I have the same problem with my pfsense:

2.0.2-RELEASE (amd64)
built on Fri Dec 7 22:39:43 EST 2012
FreeBSD 8.1-RELEASE-p13

and Varnish 3.0.2 pkg v.0.1

I tried all suggestion you gave but nothing solve my problem: when I call the Varnish on litening port (8082 in my case), only the firt defined backend is returned, no change if I call www.call1.com or www.call2.com (both domains point to public ip of pfsense of course).
this is the configuration:

backend crmBACKEND {

used in catch_all

.host = "10.8.0.1";
.port = "51231";
.first_byte_timeout = 100s;
.connect_timeout = 100s;
.probe = {
.request =
"GET /diagnostico.asp HTTP/1.1"
"Accept: text/*"
"User-Agent: Varnish"
"Host: www.site1.com"
"Connection: Close";
.interval = 10s;
.timeout = 100s;
.window = 1;
.threshold = 1;
}
}

backend wwwBACKEND {

used in catch_all

.host = "192.168.1.2";
.port = "80";
.first_byte_timeout = 100s;
.connect_timeout = 100s;
.probe = {
.url = "www.site2.com";
.interval = 10s;
.timeout = 100s;
.window = 1;
.threshold = 1;
}
}

sub vcl_recv {

if (req.http.host == "www.call1.com") {
set req.backend = crmBACKEND;

}
else if (req.http.host == "www.call2.com") {
set req.backend = wwwBACKEND;

return(lookup);
}

sub vcl_pipe {

If we don't set the Connection: close header, any following

requests from the client will also be piped through and

left untouched by varnish. We don't want that.

set req.http.connection = "close";

Note: no "pipe" action here - we'll fall back to the default

pipe method so that when any changes are made there, we

still inherit them.

sub vcl_hit {

sub vcl_miss {

sub vcl_fetch {

#Disable cache when backend is starting a session
if (beresp.http.Set-Cookie && beresp.http.Set-Cookie ~ "(PHPSESSID|phpsessid)") {

return(hit_for_pass);
}

Varnish respects the wishes of the backend application.

if (beresp.http.Pragma ~ "no-cache" || beresp.http.Cache-Control ~ "(no-cache|no-store|private)") {
return(hit_for_pass);
}
    ## If the request to the backend returns a code other than 200, restart the loop
    ## If the number of restarts reaches the value of the parameter max_restarts,
    ## the request will be error'ed.  max_restarts defaults to 4.  This prevents
    ## an eternal loop in the event that, e.g., the object does not exist at all.
    if (beresp.status != 200 && beresp.status != 403 && beresp.status != 404 &&
    beresp.status != 303 && beresp.status != 302 && beresp.status != 301 && beresp.status != 401 ) {
set beresp.saintmode = 60s;
return(restart);
        }

set beresp.grace = 30m;
return(deliver);
}

sub vcl_deliver {
##set resp.http.X-Served-By = server.hostname;
  if (obj.hits > 0) {
    set resp.http.X-Cache = "HIT";

what backend status you get on dashboard varnish widget?

both up with green arrow
no other value is shown in the fields "cache hits" etc., just shows the two backends with status

thanks
