There's no problem on my machine, but on the server, whenever I try to upload some files, and then click on "Save", it shows me an error "Closed file cannot be accessed". On Googling it, I read here that this was due to large files being uploaded. I wanted to confirm, is the problem that I'm uploading large files?? Or could it be something else? Also, why am I not getting this on my machine and only on the server?? EDIT: By the way, the error showed up when the file size > 80kb Code on Uploading file: public ActionResult StoreLogoInSession(HttpPostedFileBase file, int assetID) { string filename = null; if (ValidateOnUpload(file)) { Session.Add("TempLogo", file); filename = file.FileName; Session.Add("filename", filename); } return RedirectToAction("Edit", new { id = assetID }); } Code on Saving (this is when the error occurs): public ActionResult SaveLogo(LogoModel m, int assetID) { HttpPostedFileBase file = (HttpPostedFileBase)Session["TempLogo"]; var logoModel = new LogoModel(); var as

On my local system, every thing was just fine. but when i deployed my application on development server, my control was able to upload only small size files. whenever i tried to upload large size file i got error "cannot access a closed file" After going through MSDN i found that there is one new element added in ASP.NET 2.0 known as httpRuntime. So i just added this new Tag in my web.config and every thing was right.
