Subject Re: [FileUpload] Issue with multipart/form-data and request parameters in include
Date Fri, 26 Aug 2005 19:27:48 GMT

Is there a reason that the URL parameters can not be included as a 
hidden field in the form?  i.e. Instead of setting a form tag with the 
action set to "resource.jsp?param=value".  Set up your form to post the 
value with the form as a hidden form field set up

<form name="form" id="form" method="post" action="resource.jsp" 


   <input type="hidden" name="param" value="value" />



This would be much easier and more reliable that trying to make 
commons.fileupload much more complicated.

If you have to do it the way you outlined then you might be able to pull 
that value out of the HttpHeader object.
