[Agavi-Users] Remove Pragma http-header

[Michal Charemza]

Hi,

I'm trying to make sure that certain views *are* cached (in the
browser / proxies), so I'm setting the cache-control, expires headers
appropriately. I'm also trying to prevent the "Pragma" http header
from being sent. In a view the following does not seem to have an
effect:

$this->getResponse()->removeHttpHeader('Pragma');

However the following does seem to remove the header (according to
Firebug)

$this->getResponse()->setHttpHeader('Pragma', '');

Can I check that doing the latter is ok, and will suffer not bad
consequences?

Michal.

Hi Michal,

This code

> $this->getResponse()->removeHttpHeader('Pragma');

does not remove the Pragma Header since this header is set by php
itself (most probably by session_start() in your case) and thus is not
managed by agavi.

This code

> $this->getResponse()->setHttpHeader('Pragma', '');

Overwrites the header set by php with an empty value. It should not
have any side effects. You can use curl or any other low level http
lib to check whether the header is really removed.

Thank you!

You might however prefer to simply configure it in factories.xml:
<response class="AgaviWebResponse">
<ae:parameter name="http_headers">
<ae:parameter name="Pragma"></ae:parameter>

That should work just as well.
