Signed applet to upload Wav file

I m using signed applet to create a wav file and upload to the server. at the server side i am using perl scrit for upload.

process goes like this,

applet reads the wav file and writes byte stream by opening http connection to perl file. at the server side perl programs reads from STDIN in binary mode and writes to a new file with random name.

this works fine.

Now, i want to send the file name also, so that at the server side, uploaded file can have expected file name.

How do i do this...?
