When uploading a file through asp.net is there any way to intercept the upload befor the file is beeing saved by my asp.net code? This is im working on is an upload page. People have a certain amount of quota to upload to. If they upload large files and quota is expired the file is first uploded, i dont know where to but i supose to a temp directory set by the webserver, then when its done they get a message saying that the uploaded file was not saved due to insufficient space. Thats a problem cause the file is first uploaded then they get a message that it wasnt saved. I want to intercept the upload before the file is uploaded to the webserver. Is there any way to accompish this?? Any ideas is very welcome.
