When setting a cookie, the old ones are lost

Thank you for the advices, in this scenario I am forced to use a cookie because I want to make a 307 redirect every time varnish would send 503 to borwser, but I need to send a cookie to prevent redirect loops.
If you have any solution for this, your advice will be highly appreciated.
I tried this way: set resp.http.set-cookie = resp.http.set-cookie + ";foo=bar"
but it didn't work for me. Are you sure this method should work or I am forced to use the vmod that Paul suggested ?
Thank you very much

The problem is that there can, according to the IETF, only one Set-Cookie header. What you want to so is to modify the exsisting set-cookie header.
set resp.http.set-cookie = resp.http.set-cookie + ";foo=bar"
You could add another Set-Cookie header as Paul proposed but that breaks the spec, all though it will probably work for at least 99% of the clients out there.
