When you run this function? after each requests ? but if so, the client is
able to read the image before you delete it ?<br>

all,<br>
<br>
I have a demo where I'm using mapserver cgi interface. I'm using the browse
mode so each time mapserver receive a request, it creates a temporary png
on the server filesystem. <br>
<br>
Do you know how and when i can delete those temporary image since they are
used only one time ? <br>
<br>
An attacker could easily fill all the server HD locking all the
system.<br>
<br>
Thanks<br>
