hi all, sorry if this is a little of topic but I hope some out there
can give some help.
I have configured kannel for sending wap messages and works fine, but
now I have another problem and would like to know if some one could
give me a tip or hint for solving the following issue:
I am using WAP for sending jpg images, the images are stored out of
the DocumentRoot and based on a php session and using the following
code I send the image:
I send this to the phones: http://mysite.com/content.php?
sid=12345678912345678912345678911100
where sid is the session_id generated when the phone request a
content, and there on the session is stored the path of the image
Then content.php has something like this:
<?php
session_id($_GET['sid']);
session_start();
$cache = $_SESSION['file'];
$imginfo = getimagesize($cache);
$content_length = filesize($cache);
$mime = $imginfo['mime'];
header('Content-Length: '.$content_length);
header("Content-Type: $mime");
header('Content-Disposition: attachment; filename="'.$cache.'"');
readfile($cache);
?>
this code works when the images are lower than 10k but I started to
notice that when the images are 10k the phone just can not download
the image what I do in does cases, is to move the images to the
DocumenRoot and use the following code:
<?php
session_id($_GET['sid']);
session_start();
$file_path = $_SESSION['file'];
header("Location: http://mysite.com/storage/images/$file";);
?>
This code just redirects the phone to the path where the content is
inside the Documentroot , and the jpg image can now be downloaded
with out any problem, but any other user can now later just copy the
URL and fetch the content and that is what i want to avoid.
I would like to know if some one can give me an idea of how to secure
the content and how could I send images larger than 10k using php
functions maybe like readfile for geting the content that is out of
the Documentroot.
Right now i am trying to figure how to use WML and php readfile(),
hoping this could help me.
Regards.
