File Name Length

Question

Hi All,
While down loading .csv file, i can get my file name length dynamicallly upto 157 bytes but not getting more than that.
I have a requirement to download very long file name. Can any one please suggest me a good solution?.
My code is
response.setContentType(contentType);
                    response.setCharacterEncoding("WINDOWS-932");
                    response.setHeader("Content-Disposition",
                              "attachment; filename="
                                        + URLEncoder.encode(fileName, "UTF-8"));-vignesh

It seems there is no restrictions in filename's maxlength.
However, if you check the section 2.3 of this link
[http://www.faqs.org/rfcs/rfc2183.html|http://www.faqs.org/rfcs/rfc2183.html]
It says:
It is important that the receiving MUA not blindly use the suggested
filename.  The suggested filename SHOULD be checked
(and possibly changed) to see that it conforms to local filesystem conventions,
does not overwrite an existing file, and does not present a security problem
(see Security Considerations below).I tried to test filename's maxlength with different browsers and found that results differ with browsers.
The HTTP response header nevertheless contained the full filename.
Above all, IMO avoiding long filename is the best solution.
