Override Default Headers

From: http://groups.google.com/group/joomla-dev-general/browse_thread/thread/6ef5fe7eba4efc26

How can I override the default joomla headers from within a custom component? I would like to change

JResponse::allowCache(true) did the trick. If it helps anyone else, here is the code that worked for me. 

JResponse::allowCache(true); 
JResponse::setHeader('Pragma', 'public',true); 
JResponse::setHeader('Cache-Control','public',true); 
JResponse::setHeader('Expires', gmdate('D, d M Y H:i:s', time() 
+(60*60*5)) . ' GMT',true);

Override Default Headers

From: http://groups.google.com/group/joomla-dev-general/browse_thread/thread/6ef5fe7eba4efc26

How can I override the default joomla headers from within a custom component? I would like to change

JResponse::allowCache(true) did the trick. If it helps anyone else, here is the code that worked for me. 

JResponse::allowCache(true); 
JResponse::setHeader('Pragma', 'public',true); 
JResponse::setHeader('Cache-Control','public',true); 
JResponse::setHeader('Expires', gmdate('D, d M Y H:i:s', time() 
+(60*60*5)) . ' GMT',true);
