Dear List,

I have a problem with IE cache:
I generate PDFs from java servlets with iText.
These PDFs contain  personal  data.
In this case I would like to remove these PDFs from client IE cache.
I can't set clients IE settings.

I have https connection. I have the http head settings that work on html 
pages, but not wok with PDFs:
Cache-Control: no-store
Pragma: no-cache
Expires: 0

With these settings it works with html pages (e.g. if you  press "back 
history" button, the  html page will  be removed from cache), but 
does'nt work with PDF pages (the PDF file is not stored in cache, 
therefore Acrobat Reader can't find it -> page not found error).

If I use these settings with http (not with https), it works properly.

Best Regards,
    Ferenc
