how to set cache control at header level in web service?

Hi,
I tried doing this :
request.setHeader('Cache-Control','public,max-age=43200');
but still when I checked response in rest api. I can't see my value at max-age, it's still displaying like this :
Cache-Control: no-cache,must-revalidate,max-age=0,no-store,private

Please help me with this on how to proceed further on the same.

Thanks in advance..!!

Set the value in RestResponse not in RestRequest then your api response will show the correct value. 
RestResponse res = RestContext.response;
res.setHeader('Cache-Control','public,max-age=43200');

Hi Asif,

Thanks for your rpl. I tried this :

RestResponse res = RestContext.response;        
//httpResponse response = new httpResponse();  
 res.setHeader('Cache-Control','public,max-age=43200');

But the above code is throwing some error :
Method does not exist or incorrect signature: void setHeader(String, String) from the type System.RestResponse.

Please help me with the same.

Thanks

I thought your webservice is a REST service so gave that code.
If you are using httpResponse() then try the below code 
response.setHeader('Cache-Control','public,max-age=43200');

Hi Asif,

Thanks for your help.
But it is working perfectly for me. Instead of setHeader I used addHeader() and it worked.

Appreciate your response..!!:)
