Varnish, Apache2 och Edge Side Include (ESI)

Well, hur ser din varnish-conf ut? Hur skriver du ut esin?

Jag kör med varnish 2.1.5.

## Redirect requests to Apache, running on port 8000 on localhost
backend apache {
        .host = "127.0.0.1";
        .port = "9002";
}
## Fetch
sub vcl_fetch {
                ## Remove the X-Forwarded-For header if it exists.
        remove req.http.X-Forwarded-For;

                ## insert the client IP address as X-Forwarded-For. This is the normal IP address of the user.
        set    req.http.X-Forwarded-For = req.http.rlnclientipaddr;
                ## Added security, the "w00tw00t" attacks are pretty annoying so lets block it before it reaches our webserver
        if (req.url ~ "^/w00tw00t") {
                error 403 "Not permitted";
        }

        esi;  /* Do ESI processing */
        unset beresp.http.set-cookie;
        set beresp.ttl = 60s;

                ## Deliver the content
        return(deliver);
}

## Deliver
sub vcl_deliver {
                ## We'll be hiding some headers added by Varnish. We want to make sure people are not seeing we're using Varnish.
              ## Since we're not caching (yet), why bother telling people we use it?
        remove resp.http.X-Varnish;
        remove resp.http.Via;
        remove resp.http.Age;

                ## We'd like to hide the X-Powered-By headers. Nobody has to know we can run PHP and have version xyz of it.
        remove resp.http.X-Powered-By;
}

Sedan testade jag först med två filer, foo.html och foo2.html:

foo:html

<esi:include src="/foo2.html" />

foo2.html:

bar

Jag testade även med

<esi:include src="http://localhost/foo2.html" />
