EAUpload is an ASP.NET file upload component that provides expansive functionality for ASP.NET applications to work with uploaded files to the web server by a browser. It conforms to the specification that is defined in RFC 1867 (Form-based File Upload). EAUpload doesn't require any client side control such as ActiveX or Java applet, but if you use any client side control then EAUpload can still operate with file which was uploaded by these controls. Core of EAUpload is a EAUploadModule that handles and processes upload request to any or specified resources in ASP.NET application. Uploaded files are buffered to disk. It protects a web server from a memory leakage. EAUpload also includes a simple way to guard against denial of service attacks. It provides a possibility to limit the size of the files which can be uploaded to the web server.
EUpload has many advanced features such as: large files upload (up to 4GB limited by IIS web server); multiple files upload by one request; provides detailed information about uploaded file; provides advanced upload status information; compatible with SSL (HTTPS) and any kind of authentication; custom handling of exceptions, etc. Distribution package includes many various examples written in C# and in VB.NET for Visual Studio 2003, 2005 and 2008.
