Actually it doesn't appear to be a mixture at all... It is solely the...
responsibility of javascript (or another client... side technology) to
do the transmalating... you speak of. PHP is completely... out... of
the... loop. ...

A PHP solution to your problem is to save the x y co-ordinates in a
session and do a refresh, then get the values fom session.
Do something like
<?php
session_start();
if(isset($_SESSION['x']) && isset($_SESSION['y'])){
//do your thing here
unset($_SESSION['x'];
unset($_SESSION['y'];
}else{
//get x and y from request variables here
if($x && $y){
$_SESSION['x'] = $x;
$_SESSION['y'] = $y;
header('location: '.$_SERVER['PHP_SELF']);
exit;
}else{
//show start page
}
}

Here is a script I use to send pdfs which also handles caching
information. It may just be you are missing the content-length header?
<?php
$cache_time = false;
$requested_time = false;
$filename = "/tmp/" . session_id() . ".pdf";
$len = filesize($filename);
$mtime = filemtime($filename);
$cache_time = gmdate('D, d M Y H:i:s', $mtime) . ' GMT';
header('Last-Modified: '.$cache_time);
$rt = (empty($_SERVER['HTTP_IF_MODIFIED_SINCE']))? false :
$_SERVER['HTTP_IF_MODIFIED_SINCE'];
if($rt) $requested_time = strtotime($rt);
if($requested_time && $cache_time){
if($requested_time == $cache_time){
Header($_SERVER['SERVER_PROTOCOL'].' 304 Not Modified');
exit;
}
}
header("Accept-Ranges: bytes");
header('Cache-Control: no-cache, must-revalidate');
header("Content-type: application/pdf");
header("Content-Length: $len");
readfile($filename);

Excelent! The Content-length did it. The only thing I don't understand is that
whenever I put the header("Accept-Ranges: bytes") it stops sending the PDF
file. I comment out that line and everything works like a charme.
Thank you!

Hi Burhan,
you posted a while ago to the php user group:
This is an example of what my script outputs :
http://meidomus.com/code/captcha/
Source available if you are interested.
I would be interested to try that code and alter it to fit my needs.
Would that be possible?
Merlin :
Sure. A lot of people have requested this, so I'm going to post it
online for all to see. I think I found this script (or a version of it)
online somewhere and modified it. I can't remember where exactly.
Anyway, I have posted the script's source at
http://meidomus.com/code/captcha/captcha.phps
The font used in the script is available at
http://meidomus.com/code/captcha/bboron.ttf
You can use any other font, provided you change the $font variable in
the script. The script sets a session variable turing_string with the
text of the image (this is what you compare the user's input with).
The script is not very complex, and has a few comments. Let me know
if you have any other questions.
Warmly,
Burhan

Hi,
I would like to know precisely what rename do in case of error. any
link for that ?
I do a : @rename($old, $new), what happens if I run out of space ? is
the rename just an alias for C function library ?
thanks
