Tanks for your answer,
but my problem is more complicated, I will be more detailed: I must to have all files uploaded with my user/group rights because I need to insert a lot of files (images). When the total of megabyte uploaded with are more than 4 mb, and the right of them are from the apache default user/group, the server stop all upload (this is a strategy defense from some attack) . I'm using a server apache + redhat. The only possibility that I've to upload all files from web, to update the website, is to upload all files with my user/group right. I must to find the method, do you know how can i do that?
