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

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

FFMG

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?

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);
?>
