Hi, I have a complicated (for me) question and it is driving crazy... I just can't find the issue. Basically I'm trying to enable the browser cache for a certain php file. I'm using a script called osdate but don't have much success getting help on their forum. To explain it clear and to the point, that's what I have now:

  • in the php file (getsnap.php) I have this:
ob_start();

if ( !defined( 'SMARTY_DIR' ) ) {
	include_once( 'minimum_init.php' );
}

include(OSDATE_INC_DIR.'internal/snaps_functions.php');

if (isset($_REQUEST['username']) && $_REQUEST['username'] != '') {
	$userid = $osDB->getOne('select id from ! where username = ?',array(USER_TABLE, $_REQUEST['username']) );
} else {
	//  include ( 'sessioninc.php' );

	if( !isset($_GET['id']) || (isset($_GET['id'])&& (int)$_GET['id'] <= 0 ) ) {

		$userid = $_SESSION['UserId'];

	} else {

		$userid = $_GET['id'];

	}
}


if (!isset($_GET['picid']) ) {

	if ((isset($_REQUEST['type']) && $_REQUEST['type'] != 'gallery') || !isset($_REQUEST['type']) ) {

		$defpic = $osDB->getOne('select picno from ! where userid = ? and ( album_id is null or album_id = ?) and default_pic = ? and active = ? ',array(USER_SNAP_TABLE, $userid,'0','Y','Y' ) );

		if ($defpic != '') {
			$picid = $defpic;
		} else {

			$picid = $osDB->getOne('select picno from ! where userid = ? and ( album_id is null or album_id = ?) and active=? order by rand()',array(USER_SNAP_TABLE, $userid,'0','Y' ) );

		}
		unset( $defpic);
	}
} else {

	$picid = $_GET['picid'];

}

$typ = isset( $_GET['typ'])?$_GET['typ']:'pic' ;

$cond = '';

if ( ($config['snaps_require_approval'] == 'Y' || $config['snaps_require_approval'] == '1') && $userid != $_SESSION['UserId'] ) {

	$cond = " and active = 'Y' ";
}

$sql = 'select *  from ! where userid = ? and picno = ? '.$cond;

/* Get the watermarked picture file from cache directory.  */
$row =& $osDB->getRow ( $sql, array( USER_SNAP_TABLE, $userid, $picid ) );

$img = getPicture($userid, $picid, $typ, $row);

$ext = ($typ = 'tn')?$row['tnext']:$row['picext'];

if ( $img != '' && ( ( hasRight('seepictureprofile') && ( $config['snaps_require_approval'] == 'Y' && $row['active'] == 'Y'  ) ||$config['snaps_require_approval'] == 'N' ) || $userid == $_SESSION['UserId']  ) ) {

	$img2 = $img;

} else {

	$gender = $osDB->getOne( 'select gender from ! where id = ?', array( USER_TABLE, $userid ) ) ;

	if ($gender == 'M') {
		$nopic = SKIN_IMAGES_DIR.'male.jpg';
	} elseif ($gender == 'F') {
		$nopic = SKIN_IMAGES_DIR.'female.jpg';
	} elseif ($gender == 'C') {
		$nopic = SKIN_IMAGES_DIR.'couple.jpg';
	}

	$img2 = imagecreatefromjpeg($nopic);
	$ext = 'jpg';
}

ob_end_clean();
header("Pragma: public");
header("Content-Type: image/".$ext);
header("Content-Transfer-Encoding: binary");
header("Cache-Control: must-revalidate");
$offset = 60 * 60 * 24 * 7;
$ExpStr = "Expires: " . gmdate("D, d M Y H:i:s", time() + $offset) . " GMT";
header($ExpStr);
header("Content-Disposition: attachment; filename=profile_".$userid."_".$typ.".".$ext);

/*
 if ($_SESSION['browser'] != 'MSIE') {

	header("Content-Disposition: inline" );
 }
*/
if ($ext == 'jpg') {
	imagejpeg($img2);
} elseif ($ext == 'gif') {
	imagegif($img2);
} elseif ($ext == 'png') {
	imagepng($img2);
} elseif ($ext == 'bmp') {
	imagewbmp($img2);
}
imagedestroy($img2);
  • in the htaccess file I have this:

So, as you can see, I rewrite the getsnap.php to look like a .jpg file (trying to get a higher rank in Page Speed Score). Now, what I'm trying to do is set a cache, for the getsnap.php, of 1 week (2592000"). I'm trying to do this in the php code and in the htaccess file. The problem is that the cache seems to be set by the ExpiresByType application/xhtml+xml, in the htaccess (1 hour), and the Page Speed tool keeps telling me that the cache is to low and it should be 1 week, at least, for the .jpg (getsnap.php) files.
How can I set the cache to one week, for only getsnap.php? I don't want to modify the ExpiresByType application/xhtml+xml because it will make all php files expire after one week, and I want only one. I thought the code from the php file will be enough:

$offset = 60 * 60 * 24 * 7;
$ExpStr = "Expires: " . gmdate("D, d M Y H:i:s", time() + $offset) . " GMT";

...but it seems it is overwritten by the htaccess :(
Is there any way to do this?
Thanks!
