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

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 ?

RE: [mapserver-users] disk space

2008-10-23 Thread Fawcett, David 
Valerio, 
 
I think that most people just set up a cron job or a scheduled job on their 
server to delete all of the temporary images at some periodic interval.  (e.g. 
24hrs, 12hrs, 1hr)  Your interfval would depend on the number of images that 
you are generating, disk space, etc.
 
In the code that you use to delete the files, you may want to look at the 
timestamps on the images and only delete images that are at least 1 minute old, 
so you don't accidentally delete an image before it can be used by the page 
that called it.
