regex - Using Varnish 3 to set cookies -

I am trying to set a cookie using varnish but I do not know how many headers of the same name How is the treatment done. For example, if multiple cookies need to be set, the application will be sent:

  set-cookie: source = source + 2; Expired = Tuesday, 04-Nov-2014 17:12:50 GMT; Path = /; Domain = .xampp.com.local set-cookie: someOtherCookie = othervalue; Expired = Tuesday, 04-Nov-2014 17:12:50 GMT; Path = /; Domain = .xampp.com.local  

I want to set a cookie in any varnish, but if back-end response contains a set-cookie header or if the client is already Cookies, I have to make sure that I'm not destroying them in the process of setting their cookies.

Adds the heading `$ UUID` to the header, or use SID # from the head SID URL if (req.url ~. [And?] SID = ([^ & amp;; +). *") {Set Req.http.x-Varnish-Faked-session = regsub (req.url, ". * [And?] SID = ([^ & amp;; +]. *. *", "Frontend = \ 1");} and {C} {UUID_Buff [50]; generate_uuid (uuid_buf); VRT_SetHdr (SP, HDRURU, "\ 030 X-Varnish-Fuk-Session:", UUID_BIF, VRT_majic_string_and);} C} if (req.http.Cookie) {# client sent us cookies, try not to shock just one frontend cookie # away Additional cookies std.collect (req.http.cookie); set req.http.cookie = req.http.X- varnish-baked-session + ";" + req.http.cookie;} other {set req.http. Cookie = req.http.X-varnish-baked-session;}} Sub Generation_session_expires {# set X-Varnish-cookie-ends now + esi_private_ttl in format: # Tues, February 19, 2013 00:14:27 GMT # This is not a threadseaf but in this case it should not make any difference. {Time_t = time (zero); Struct tm now_tm = * gmtime (and now); Now_tm.tm_sec + = 3600; Mktime (& now_tm); Four dated df [50]; Spartime (date_book, size (date-ABF) -1, "% A,% D-% B-% Y% H:% M:% S% Z," and now_TM); VRT_SetHdr (SP, HDROSSAP, "\ 031X-Varnish-Cookie-Expires:", date_buf, vrt_magic_string_end); } C}

and checking to see that the user already has a forward cookie:

  if (req.http.Cookie ! ~ "Frontend =") {# This is a real user, call gener_session to create a new session for them; }  

So, how do I deal with those cases where one or more of the following are generated:

• Frontend for Varnish Megato = Add cookie
• The backend is returning one or more cookies
• Customer already has one or more cookies

You will need header vmod for this:

Example:

  header.append (beresp. Http.Set-cookie, "stayAtLocale = 1");  

You can also use std vmod in all of the titles in "Compact":
