How to Set Headers to Cache Search Results

[Julie H]

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

Expires: Mon, 1 Jan 2001 00:00:00 GMT
Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-
check=0
Pragma: no-cache

to

Expires: ~in five hours~
Cache-Control: public
Pragma: public

In my component, I have included the following code

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

but the page is still sending out the default joomla values for
Expires, Pragma, and Cache in the http header.

Any help would be greatly appreciated.

Thanks,
Julie

Hello everyone,

Does someone have an idea why the file that containt my class derived from JView is called view.html.php instead of view.php, I get: 500 - View not found?

Thanks,
Have a great day!

Just found out that I erased

$document->getType()

in

$view = &$this->getView(SETTING::$View, $document->getType());

Thanks everyone.

I am also unable to set my headers using setheader().

I dont see any expire tags in my default joomla template.

Not finding much documentation on this.

Pretty certain JResponse::setHeader is what you're after:
http://api.joomla.org/Joomla-Framework/Environment/JResponse.html#setHeader

Just looking at things, you also might want to set
JResponse::allowCache(true) as well to prevent JResponse setting those
headers as well.

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);

Thanks!
