how to read the HttpRequest twice

Hello,

Is there a way to read a HttpServletRequest inputStream twice?

I have made a deep copy, but in so doing have gone to the end of the stream.

I want to use the apache fileupload code to look for request parameters in the inputStream. Using the apache fileupload requires the request itself to be used as a parameter, so I can't use the copy.

I value your response!

What you are doing sounds like a bad idea (a deep copy? what for?) but the usual way to read an InputStream twice is to wrap it in a PushbackInputStream with a suitably large buffer size.

Why aren't you just using one of the 3rd-party packages that handles this for you?

Hello,

I am processing a multipart fileupload request.

The first step is to read one of the request parameters and validate it.

The next step is to write the entire request inputStream to disc.

I am using apache fileupload jar file to get the request parameter from the stream.

So you see I need two passes of the request inputstream to fulfill my requirements.

Why would you want to do that?

This is the requirement. The file must be in this format to be read by the rest of the system.

Thanks.

I ask again, why aren't you using one of the popular libraries to handle the multi-part request?
