Hi, I have an application where I based on users selections generate a dataset for them to download and a graph describing this data. The graph is made with gnuplot and work really well - no problems :-)
But I save the graph to a file say "graph.png" in the public/images dir and use it in the view. I have a strong felling that when more than one user is generating graphs I will have a problem, since they'll keep overwriting the same graph again and again. I realize that I could add some sort of session id or time stamp to the image, but I don't want to fill my server with abandoned images and the users are not likely to request the same image/graph again any time soon. Is there any concept like a temp store where all files more than 5 mins (or 1 day, don't matter :-) old are deleted, or a round robin scheme where abandoned filenames get recyled. Have I missed some vital function, - or is it just a matter of a cron job to clean up after a hard days job? regards Jan -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
