Hi Tim -
I've had mixed experiences using servlets to stream files back to
IE. Mime types aren't recognized, text files are displayed automatically
(w/o the Save dialog being displayed first), etc. Currently I use this bit
of code to do the job & (most of the time) it does OK.
================
res.setContentLength((int)new File(file.getPath()).length());
res.setHeader("Content-Disposition", "attachment; filename=\"" +
file.getName() + "\""); //see
http://www.ietf.org/rfc/rfc1806.txt?number=1806
res.setContentType("application/octet-stream");
byte[] buffer = new byte[4096];
try
{
OutputStream out = res.getOutputStream();
FileInputStream in = new FileInputStream(file.getPath());
int c;
while((c = in.read(buffer, 0, 4096)) > -1)
out.write(buffer, 0, c);
out.close();
in.close();
}
catch(IOException e )
{
e.printStackTrace();
}
================
It works fine with PDF files & IE 5; not sure about other versions
of IE.
Best of luck,
Tom

Subject: Internet Explorer 5.0 does not handle redirects to pdf files
The company I work for is using a servlet to log requests for documents on
our
site. The way this works is that the link for the document actually goes
through a servlet I wrote, which logs the request and issues a redirect to
the
"real" url. This has been working fine, but recently we discovered a
serious
bug involving Internet Explorer and redirects to .pdf files. If you click
on
the url which goes through the servlet, the browser hangs for a bit, and
then
finally returns "unable to find object to handle request".
Note: This works FINE with all other browsers we've tested.
To test this, I wrote a very simple servlet which only issues a redirect to
a
pdf file we host, and it fails too. We suspect this is something related to
mime-types, and hence I tried setting the mime-type to "application/pdf"
before
issuing the redirect in the servlet above, but it had no effect and
ellicited
the same behaviour. Is the <gasp> an IE bug? Does anyone know of a
workaround?
Platform:
ApacheJServ 1.1.1, ibm jdk 1.18 for Linux, JSDK2.0
Can anyone shed some light on this?
Thanks much,
-Tim
