Assert error in VRT_ESI

Thu Jan 28 12:02:25 CET 2010

Hi everybody,

I'm trying to experiment with ESI but even the simplest setup crashes.
My setup is FreeBSD 7.2, apache 2.2.14, varnish 2.0.6 from ports.

I have a simple page:

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

include.html
<p>Test</p>

When I open it through Varnish the connection is reset. Requesting 
include.html directly is no problem.

My default.vcl:

backend dev {
   .host = "192.168.2.10";
   .port = "80";
}

sub vcl_recv {
     if (req.url ~ "\.(js|css|gif|jpg|png|ico|txt|swf|mp3)(\?.*)?$") {
         unset req.http.cookie;
     }

     if (req.http.Accept-Encoding) {
         if (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;
         }
     }

     if (req.url == "/index.html") {
<------>esi;
     }
}

What happens:
