Sessions across servers?

[CK]

I'm try to implement a CATCHPA script on a server that doesn't have GD
extension. So i'm calling a PHP script on another server to return the
image. Only problem is I need to return a variable along with the
image as below

On server 1(Without GD)
<img src="http:www.server1.com/image.php?
width=100&heigh t=40&characters =5" />

ON server 2(Image creation and security code scipt)
..........
header('Content-Type: image/jpeg');
imagejpeg($imag e);
imagedestroy($i mage);
$_SESSION['security_code'] = $code;
..........

Script works fine if all files on server with GD extension, my only
problem is getting back the "$_SESSION['security_code'] = $code;"
variable?

Thanks

Hi,

No, you cannot easily share session between different servers.
Unless you want to get into the detail of it, my advise would be to
simply use recaptcha:

http://recaptcha.net/

Using that also:
1) Makes sure your captchas are difficult enough, but readable
2) Makes your captcha even work for visual disabled/impaired visitors
3) You help translate books!
4) Very easy to set up and use.
5) public/private key logic implemented, so hackers/spammers will have a
hard time.
