Lighttpd

Hi all,

I am using embedded device with lighttpd 1.4.45 + cgi module. The client downloads file from lighttpd server, then the CGI module will be called to send random data content from memory with the client specific file size. For example, if the client requests 100M file size, then the CGI program sends 100M contents out from memory.

However, I found that when the client downloads file, the /var/tmp will also generate total 100M files which are names with prefix "lighttpd-upload-". And it will deletes after the client downloads file complete. From the document https://redmine.lighttpd.net/projects/lighttpd/wiki/Server_upload-dirsDetails, I know that this is used for file upload, not file download. So, why I download the file from lighttpd server, it will generate random file? Is it a bug?

Please note that I run this on embedded device, therefore, the RAM and Flash resource is limited.
