 Hi,

 After updating varnish from 2.1.2 to 2.1.4. I'm having problem with double
 Content-Length header. Here is my VCL:


 {{{
 sub vcl_recv {
 if ( req.url == "/" ) {
 return (pass);
 }
 }

 }}}

 My backends are apache servers, which handle req.url == "/", they send 301
 redirect, based on user-agent. Apache sends proper Content-Length header,
 and varnish doubles it adding same header with identical size. Some mobile
 clients can't deal with doubled headers.

 I managed to overcome problem with this VCL snippet:

 {{{
 sub vcl_fetch {
 if (beresp.status == 301) {
   unset beresp.http.Content-Length;
 }
 }
 }}}
