Servlet coming as file download

[Carlos Roberto de Oliveira Queiroz]

    Hello, I have a Apache 2.0.50 with an active mod_deflate connecting to Tomcat 
(4.x) via mod_jk2. After I activated deflate, sometimes when I call a servlet IE 
doesn´t open the page with the servlet response, but a file download window as if I 
was trying to download a file named 'servlet'. Can anyone please suggest a solution ?

Thanks
