ah the old IE + SSL + cacheing problem ;)
Try adding:
final String userAgent = request.getHeader(user-agent);
if (response.containsHeader(Pragma)
userAgent!=null
userAgent.toUpperCase().indexOf(MSIE)-1) {
response.setHeader(Pragma, public);
}
Solved it for us.

Hi,
I have a serlvet that is used to download a file to the client.
I am using Tomcat 4.1.24, with IE6.
All is fine when no security-constraint is applied in the deployment
descriptor, but when I introduce such a constraint the file cannot be
downloaded. I recieve the error:
Internet Explorer cannot download servlet?d=file.pdf from localhost.
My code to download is:
try {
String filename = spec1.pdf;
String downloadType = application/pdf;
response.setContentType(downloadType+; name=\+filename+\) ;
File file = new File(/ + filename);
FileInputStream in = new FileInputStream(file);
response.setContentLength((int)file.length());
byte[] buf = new byte[4 * 1024]; // 4K buffer
int bytesRead;
while ((bytesRead = in.read(buf)) != -1) {
out.write(buf, 0, bytesRead);
}
}
finally {
if (in != null) in.close();
}
I found some references to setting the content-dispostion header however
setting this did not seem to solve the problem:
response.setHeader(Content-Disposition,inline; filename=\ + filename + \;);
Any ideas/solutions would be greatly apprieciated.
Cheers
