RE: IE reloads the PDF document generated from servlet multiplet imes (2 times!)

["Sharan, Dharmendra" <Dh...@gs.com>]

Hi Savino,

     Thanks so much, it works for me.
     It definitely saves the extra time spent in reload of servlet.

     However I used the cache-control directive for IE :-

     ----------------------
     response.setHeader("Cache-Control", "max-age=10"); // workaround so IE
does not refresh/reload PDF page again/twice
     ----------------------

  regds,

  Dharmendra

This is a known issue. There seem to be several approaches, which may depend
on your particular situation. There's a full discusssion of this on the
fop-dev list under the subject 'FO -> PDF works with Netscape, not with IE'
which has the code for my solution (you can find it in the archives if not
subscribed). I believe this is also going to be in the FAQ soon. 

Please let me know if you have more questions.
