If you are using 1.1b2 or later, and you haven't explicitly configured a multipart request handler, then you're already using Commons FileUpload. One of the first things FileUpload does is check the Content-Length HTTP header against a configured threshold. If it's too big, the handler won't go any further, but will throw a FileUploadException instead. Struts catches that and also aborts processing the request at that point. What it may boil down to, though, is when the servlet is provided with the request to process. If the container buffers the entire request before calling the servlet, then you're going to have to look for a container solution, rather than a multipart handler solution. However, if the servlet is called before the request has been received in its entirety, then FileUpload, and hence Struts, should behave as you want. -- Martin Cooper > > I want to prevent someone from logging say 10 clients (or even one) and > uploading huge files which would cause the site to crash before the > check for file size is done. > > I gather there are some commercial implementations of the functionality > and also some incentivised licences (jason hunter springs to mind) but I > was wondering if this feature is available or will be available in the > near future within the commons package. > > Cheers > jfc > > > > > > -- > To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> > For additional commands, e-mail: <mailto:[EMAIL PROTECTED]> > > -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
