Solved: Question about accessing all Set-Cookie values fro... - Page 2

We have Set-Cookie values coming from our southbound, one of which we need to manipulate within the gateway before returning to the requester.

When I do the request via curl using -v, the format in the headers is:

 Set-Cookie: COOKIE_ONE=-1%2C1; Path=/ 
 Set-Cookie: COOKIE_TWO=6tuDIqNZTQl%2FqbPXU0M13tcl0nM%3D%0A%3B2015-03-12+11%3A24%3A38.766_1426173878765-214752_1_-1002%2C-1%2CUSD_1; Expires=Sat, 11-Apr-15 15:24:38 GMT; Path=/

When I try to access them within javascript using the context variable context.targetResponse.headers['Set-Cookie'], it only returns the first value. I have tried other variations as well as inspecting the value(s) of Set-Cookie within trace. I am able to get the specific one using a pattern in an extract variables policy, but I would like to have access to all of them so I can edit it and then send them along.

I know that using cookies and cookie manipulation are not really in the spirit of RESTful APIs, but this is the southbound we have to deal with and the requirements of the consumer.

I parsed this Set-Cookie header

JSESSIONID=00009H6QnwmbvT0HTm4hU3Ktvme:16kfvo759; Path=/,TSN=multi-test01; expires=Sat,16-May-2015 02:29:01 GMT; path=/; domain=.test.dss.com,LLBSS=D; expires=Sat,16-May-2015 02:29:01 GMT; path=/

Using this:

function getVatSetCookies (values) {
   var x = 0;
   while (context.targetResponse.headers['Set-Cookie'][x]){
     context.setVariable("x-set-cookie-" + x + ".content", context.targetResponse.headers['Set-Cookie'][x]);
	    x++;
   }
   x = 0;
   while (context.proxyResponse.headers['Set-Cookie'][x]){
     context.setVariable("x-set-cookie-" + x + ".content", context.proxyResponse.headers['Set-Cookie'][x]);
	    x++;
   }
}

getVatSetCookies();

Resulted in

x-set-cookie-0.content   JSESSIONID=00009H6QnwmbvT0HTm4hU3Ktvme:16kfvo759; Path=/  
x-set-cookie-1.content   TSN=multi-test01; expires=Sat 
x-set-cookie-2.content   16-May-2015 02:29:01 GMT; path=/; domain=.test.dss.com 
x-set-cookie-3.content   DSS=D; expires=Sat  
x-set-cookie-4.content   16-May-2015 02:29:01 GMT; path=/

This works as advertised assuming the parsing of the header is being fouled up by a malformed Set-Cookie header from origin. Reading http://tools.ietf.org/html/rfc6265#section-4.1.1 the syntax of the header seems correct yet it's not parsed exactly as expected.
