Download a file from jsp

[password password <be...@yahoo.es>]

Hi, 
    I have a jsp where I show a table. I am trying to download this jsp 
like excel file. To do this I put I get the information from a servlet and send this information in an attribute to the jsp
   
  It works fine if I use only one browser. 

  The problem is when I try to do this but from 2 browsers at the same 
time. From each browser I can download a part of the file but not the 
complete file. 
It seems the browsers are sharing the bandwidth and when it starts to 
download a file the other stops. 
  Can you help me please? 
   
  The code of the servlet and jsp is the next:

    the SERVLET  has the next code:
