Re: Drupal 7.x & Varnish 3.x

When I use the code below (based on the templates at https://github.com/mattiasgeniar/varnish-3.0-configuration-templates/tree/master/conf.d), Drupal 7 + Varnish 3 'almost' works.

Varnish is working perfectly (no backend calls, two Varnish timestamps in the header).
However, I can't log in in my Drupal site. Same behaviour with directories which are protected by .htaccess. The logon screen keeps popping up when I enter the correct credentials.

My default.vcl:

/TEMPLATE/

backend default {
.host = "127.0.0.1";
.port = "80";
.connect_timeout = 600s;
.first_byte_timeout = 600s;
.between_bytes_timeout = 600s;
}

sub vcl_recv {

# A configuration file specific for Drupal 7

# Either the admin pages or the login
if (req.url ~ "/admin/?") {
        # Don't cache, pass to backend
        return (pass);
}

# Remove the "has_js" cookie
set req.http.Cookie = regsuball(req.http.Cookie, "has_js=[^;]+(; )?", "");

# Remove the "Drupal.toolbar.collapsed" cookie
set req.http.Cookie = regsuball(req.http.Cookie, "Drupal.toolbar.collapsed=[^;]+(; )?", "");

# Remove any Google Analytics based cookies
set req.http.Cookie = regsuball(req.http.Cookie, "__utm.=[^;]+(; )?", "");

# Remove the Quant Capital cookies (added by some plugin, all __qca)
set req.http.Cookie = regsuball(req.http.Cookie, "__qc.=[^;]+(; )?", "");

# Are there cookies left with only spaces or that are empty?
if (req.http.cookie ~ "^ *$") {
        unset req.http.cookie;
}

# Static content unique to the theme can be cached (so no user uploaded images)
if (req.url ~ "^/themes/" && req.url ~ "\.(css|js|png|gif|jp(e)?g)") {
        unset req.http.cookie;
}

# Normalize Accept-Encoding header (straight from the manual: https://www.varnish-cache.org/docs/3.0/tutorial/vary.html)
if (req.http.Accept-Encoding) {
        if (req.url ~ "\.(jpg|png|gif|gz|tgz|bz2|tbz|mp3|ogg)$") {
                # No point in compressing these
                remove req.http.Accept-Encoding;
        } elsif (req.http.Accept-Encoding ~ "gzip") {
                set req.http.Accept-Encoding = "gzip";
        } elsif (req.http.Accept-Encoding ~ "deflate") {
                set req.http.Accept-Encoding = "deflate";
        } else {
                # unkown algorithm
                remove req.http.Accept-Encoding;
        }
}

# Don't cache the install, update or cron files in Drupal
if (req.url ~ "install\.php|update\.php|cron\.php") {
    return (pass);
}

# Uncomment this to trigger the vcl_error() subroutine, which will HTML output you some variables (HTTP 700 = pretty debug)
#error 700;

# Anything else left?
if (!req.http.cookie) {
        unset req.http.cookie;
}

# Try a cache-lookup
return (lookup);

}

sub vcl_fetch {

# For static content related to the theme, strip all backend cookies
if (req.url ~ "^/themes/" && req.url ~ "\.(css|js|png|gif|jp(e?)g)") {
    unset beresp.http.cookie;
}

# A TTL of 30 minutes
    set beresp.ttl = 1800s;
}

/TEMPLATE/

Regards.

Sadly, no...

I tried several  configurations but still without success.
(The only 2 cookies with D7 are has_js and Drupal.toolbar.collapsed.)

Perhaps you can have a look at these Drupal templates (_drupal_7-fetch/receive): https://github.com/mattiasgeniar/varnish-3.0-configuration-templates/tree/master/conf.d
Or the one linked at drupal.org: http://drupal.org/files/issues/default.vcl_.txt


These seem to yield great results for me, with a default Drupal 7 nearly all pages can be cached.
