Re: Multiple Set-Cookie Headers

[Kenny Deckers]

Hi, Sorry that I did not elaborate this enough. Let me get into details: We are running a magento web shop with a varnish layer in front of it on a separate server. At some point, the applications has to tell Varnish that it cannot use cached content, this happens by the setting the following header: Set-Cookie: EXTERNAL_NO_CACHE=1; expires=Thu, 10-Nov-2011 15:49:57 GMT; path=/; domain=XXXXXXXXX; httponly In the default.vcl the following happens the following in the sub vcl_fetch method: if (beresp.http.Set-Cookie ~ "NO_CACHE=") { return (pass) } Since there are multiple set-cookie headers, varnish will only be able to analyze the first Set-Cookie header. This means that if-condition above fails and that it will not return a "pass" causing the application to serve cached content while it shouldn't. I have compiled the header vmod and imported it at the top of default.vcl. (import header;) And I replaced the following: if (beresp.http.Set-Cookie ~ "NO_CACHE=") { with: header.copy(beresp.http.Set-Cookie, beresp.http.X-Old-Cookie); if (beresp.http.X-Old-Cookie ~ "NO_CACHE=") { This still did not fix the issue. Thanks for responding so quickly, if there is anything else we need to let you know, please tell us. Awaiting your reply.

What issue? You are not saying anything about what you wan to accomplish. Your web server sends multiple set-cookie headers. I assume you entered the stars yourself. What are you trying to accomplish, and what have you actually tried with the header vmod? - Kristian ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.
