Summary: response containsHeader("Content-Type") not working

response.containsHeader("Content-Type") always returns false even if the header
is explicitly added via response.setHeader("Content-Type", "text/html").

To reproduce, simply add the following to a filter or servlet:

response.setHeader("Content-Type", "text/html");

The difficult question (for which the Servlet spec is silent) will be what to
return for response.containsHeader("Content-Type") if the header was set using
the response.setContentType() method.  I think the spec is pretty clear that if
setHeader is used, containsHeader should work for any header.

Thanks... Sean

This has now been fixed in SVN.

Based on the wording on the spec for setContentLength() which states that
calling this method sets the Content-Length header for HTTP servlets,
containsHeader() now returns true if the Content-Length or Content-Type has been
set directly by setHeader or indirectly by setContentLength() etc.
