imgRef = MapFunction.Map.drawQuery();
imageLoc = MapFunction.OutputDir + "/" +
System.DateTime.Now.ToBinary() + "." + imgRef.format.extension;

Thanks for the quick reply,
When you run this function? after each requests ? but if so, the client is able
to read the image before you delete it ?
best regards,
Valerio

Hi,
Why don’t you write method for deleting png .mapserver will take care about
creating an image.I have C# code.
The below code will delete all the files form OutputDIR.
I hope it helps you. Or At least you can get some idea about your task.
Thanks and Regards
Venkat.
public void Deleteimages()
{
try
{
foreach (string f in System.IO.Directory.GetFiles(OutputDir))
{
System.IO.File.Delete(f);
}
}
catch (Exception exp)
{ }
}

Dear all,
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.
Do you know how and when i can delete those temporary image since they are used
only one time ?
An attacker could easily fill all the server HD locking all the system.
Thanks
Valerio
