proxy servlet for pdf byte serving

Hi,

I have the following situation. There is a pdf streaming servlet provided by a vendor which not accessible to the outside world as the data is sensitive. What we would like to is write a proxy servlet which can pass the pdf streams back to the browser, the reason for this proxy servlet is to do some authorization to ensure that the person who is logged does indeed have access to the PDFs. If anyone could offer some example code that would be greatly appreciated.

Thanks

Do you have to pass the PDF stream? I think it is easier to get the whole PDF file and then open a new stream to the real client.

Hi,

would it not be faster if we were to take this approach, otherwise we will need to wait for the file to come through completely (this will be byte served to us) and then we will then need to byte serve the pdf to the browser.

Streaming is faster. If the file isn't very large, it wouldn't be noticeable though. I'm not sure how to do the real time streaming. Somewhat curious if it is possible now.
 
It is sorta covered in the JavaRanch Style Guide.
