Problem with HTTP Caching...?

[Lucifer.iix]

Hi there, im trying to implement caching. But it doesn't always work.

I post it here because there is no Client-Side HTTP topic...

 

private function setLastModified ($aTimestamp) {
        $this->addHeader('Last-Modified', gmdate('r',$aTimestamp), True); 
    }
     
    private function setExpires ($aTimestamp) {
        $this->addHeader('Expires', gmdate('r',$aTimestamp), True); 
    }
        
    private function setPragma ($aPragma) {
        switch ($aPragma) {
          case conResponce_NO_CASHING:      $this->addHeader('Pragma', 'no-cache', True); break;
          case conResponce_PRIVATE:         $this->addHeader('Pragma', 'private', True); break; 
          case conResponce_PUBLIC:          $this->addHeader('Pragma', 'public', True); break; } 
     } 

 

 

And this result in on the client-side:

Is:

Expires:Tue, 10 Nov 2009 12:21:58 +0000 wright?

 

Or does it have to look like:

Expires:Tue, 10 Nov 2009 12:21:58 GMT

 

I'm using: gmdate('r',$aTimestamp) and it's on the PHP site. Also i found this in a PHP book, but a lot of code of the book and the php site doesn't work at all or not properly. Im i the only one with this problems?

And why don't they remove "examples" that doesn't work?

 

 

Thanx... for reading: Lucifer
