Sending an expiry header, and then the image...

[FFMG]

Hi,

I want to send expiry headers along with my images.

This is the code in my .htaccess file

Code:
--------------------

...
#
RewriteCond $1 \.(gif|jpe?g|png|css|js|ico)$

# if the above request matches then go and get it
RewriteRule ^(.*) - [L,NC,QSA]
...

--------------------
But as well as sending the image out I would like to send an expiry
headers.
So I could change the query to something like...
Code:
--------------------

RewriteRule ^(.*) /myheader.php?r=$1 [L,NC,QSA]

--------------------
where my page 'myheader.php' would send the headers and then the image
out.

I know how to send headers, but i don't know of a php function to
'echo' the image/css.

Or maybe there is an other way, how would you send headers as well as
the image?

Many thanks

<?php
header ('X-My-Header: myValue');
readfile ('/path/to/image.gif');
?>

Thanks, do I need to send a special header with the image file?

What I mean is, would doing:

Code:
--------------------

<?php
readfile ('/path/to/image.gif');
?>

--------------------
And nothing else, be exactly the same as opening the file directly?

In my experience it has been, if you know the MIME type of the image
sending that wouldn't hurt. Ditto for the filesize, as it will allow
the client to make a time left estimate on how long it will take to
download. Sending the filesize can be done with a slightly different
approach.

<?php
$data = file_get_contents ('/path/to/image.gif');
header ('Content-Type: image/gif');
header ('Content-Length: ' . strlen ($data));
header ('Expires: '. $whatever_expire_value_i_want);
echo ($data);
?>
