Hi,
I'm writing a CGI perl script driving a dynamic website where, among functionalities implemented, files can be uploaded to the server through the browser interface, and then I want to process these uploaded files.
Since this processing (either in perl or other language) takes long time I want to start the process and go on the with script, without waiting for the end of the file processing (I'm thinking to check in other ways the result of the processing, that anyway doesn't affect the following execution) and I don't want the file submitter to hang while waiting for this processing.
I saw that exec and system wait for the process completion. How can I do this?
Thank you very much in advance.
Roberto
