doubt on response.addHeader

[kalle suresh]

I have one question on addHeader.
The difference between addHeader and setHeader is that, if the header already exists

setHeader overwrites the Header
addHeader adds new value to the Header.

suppose for example i have response.addHeader("NAME","XXX"). If i am going to add new value to NAME, how it will get added?

If you want to add one more value to Header NAME just use response.addHeader("NAME","YYY"). You can verify the two values by using request.getHeaders("NAME").It should give XXX and YYY values.Hope this helps

ok. I got it. The request will read all these values by the method
request.getHeaders().
Thanks.
