Hi Sergey - 

The response.reset did the trick. I reset the context response then built the 
ws.rs response using the response builder like before. The cache control header 
is gone.
Thank you very much.

Any explanation why this cleanup is needed and why the ResponseBuilders is 
using the context response headers? We have other request-response compiling 
some download files, running just HttpServletResponse and these seams to work 
fie with the IE8 no-cache limitation just fine by setting it to false.

In any case... The reset solved it for the REST response as well.

Subject: Re: REST response over https - no-cache always set

I run the jaxrs https test locally, without explicitly setting Cache-Control no 
such header is returned and if I call
setNoCache(false):

CacheControl control = new CacheControl(); control.setNoCache(false); return 
Response.ok().cacheControl(control).entity(doGetBook(id)).build();

then the client code shows that no 'no-cache' value is present in the 
Cache-Control header.

But the test is using the emdedded Jetty. Thus it seems like the servlet 
container that you use forces this value.

I'm looking at

I guess what you can try to do is to have

@Context
HttpServletResponse response;

injected and then do response.reset() before continuing using Response, just  
to verify it works.
If it does then you may consider  coding against the injected 
HttpServletResponse only. I'd also consider not injecting HttpServletResponse 
and instead creating a custom Servlet filter which would only do

response.reset()

before delegating further.

Let me know if it helps
Sergey
