Hello, I've developed a small Java web application that is running in an environment using Apache Web server sitting in front of IBM Websphere. We get the following behavior that we've traced to the Web server (so it never even gets to Websphere): The application allows the user to upload files to the server. I am using Apache's file upload library, but that's not the issue. The issue is described by the client in the following words: "When we try to upload a large spreadsheet, we are getting a couple of different errors but we are unable to determine the cause at this point. The Web server appears to receive the POST request from the browser and then sends a redirect (302) response to the browser. We don't know why this is happening. This is causing the browser to either display an error or to send the post request again as a GET request. The GET request fails because the browser is putting the form data in the URI, making it too big." The form in question is a simple file upload form. It is structured using post and multi-part. The symptom of the error is that a huge URL appears in the browser after hitting submit, and the explanation is as given above, i.e: the form is submitted using POST, Apache responds with a 302, and then the browser resends the request using GET but now the request URI is huge... The application fails on the server because the URI is too long when the browser sends it. Keep in mind, as the explanation above indicates, my application is not generating this huge URL: I send the form parameter using POST, and somehow things go wrong... On Sun's Application Server which is not using Apache Web server, all is well.The file is correctly and quiely uploaded... Any ideas? thanks very much in advance. - Ahmed --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
