I just read the section 4 of " head first Servlet and JSP" and worte a small Servelet to achieve download of pdf from server. I set the content type as "response.setContentType("application/pdf");" finally, it works. But I just wondering:
if the other client's browser is not support for pdf. 1.do i use setContentType("application/pdf") can add a new mine type to their browser?
2.if not, how to make it works? could something possible to change the client's browser MIME type?
3. if we can use something to add a new MIME type to Client's Browser, is it can cause the security problem? just like pass them the .exe file and run it that will be dangerous(like pass virus)?
