setHeader() and addHeader() methods

Hi,

I have a query regarding the setHeader() and addHeader() methods belonging to the HttpServletResponse class.

If the header is 'content-type' and already the header exists in the response, then setHeader() will replace the value of the existing content-type with the new value.

But how does the addHeader() method work for content-type? I think browser will be able to recognize only one content type at a time i.e. content-type header cannot have more than one value.

Please let me know how this works or correct me if I'm wrong in my understanding.

Many Thanks
Vijay

Weclome to JavaRanch.

This is one of the things that you can easily test: whether the first header takes precendence, the second, both, none, or something else. What happened when you tried it?
