Hi,

i have a Problem with uploading large Files in IE (Firefox it is ok).
Here is the first part of my fileuploadinterceptor. (i just override the
fileuploadinterceptor and added some debug messages)


public String intercept(ActionInvocation invocation) throws Exception {

   ActionContext ac = invocation.getInvocationContext();
    HttpServletRequest request = (HttpServletRequest)
ac.get(ServletActionContext.HTTP_REQUEST);
   
log.debug(ServletActionContext.getRequest()+" request: "+request);
String content_type = request.getContentType();
log.debug("contenttype: "+content_type+":
"+content_type.indexOf("multipart/form-data"));

    if (!(request instanceof MultiPartRequestWrapper) ) {
       if (log.isDebugEnabled()) {
          ActionProxy proxy = invocation.getProxy();
          log.debug(getTextMessage("struts.messages.bypass.request",
new Object[]{proxy.getNamespace(), proxy.getActionName()},
ActionContext.getContext().getLocale()));
       }

      // return invocation.invoke();
    }

    final Object action = invocation.getAction();
    ValidationAware validation = null;

    if (action instanceof ValidationAware) {
       validation = (ValidationAware) action;
    }

    MultiPartRequestWrapper multiWrapper = (MultiPartRequestWrapper)
request;


When i try to upload a file in IE i get (sometimes) this error:

21:55:48,430 MyFileUploadInterceptor.java -
