[opencms-dev] Setting manual Content-Type header from a jsp

[Stephan Hartmann]

Hi Mike,

the reason why your attempts for setting the content type by either 
using the response object or the contentType attribute in the page 
directive is that the JSP is usually embedded by using the include 
dispatcher of the request. From within an included webapp resource 
(either servlet or JSP or filter) there is no way to modify response 
headers, as defined in the servlet spec.
For your case, it would be sufficent to set the cache property of your 
JSP to "bypass" which will lead to a forward instead of an include, what 
will give you control over your response headers as well. Note that you 
will lose flex cache functionality with that property set.
Another way to set response headers from an included JSP would be to get 
hold of the top response object through the CmsFlexController object of 
your request.

Regards,
Stephan
