    pdf caching works different for browser vs reader downloads

    jpc_eng

      We have several very large pdf which are served by our web server (iis).  In analyzing the detail performance metrics we have identified an interesting behavior.  When viewing the pdf from the web link in a browser the web server quickly displays the first page then chunks the remaining parts of the document in roughly 5 kb chunks.  However, even though we have configured these to be cached they don't get cached.  But when we uncheck the Open in Browser setting in reader and allow the document to download and open with the reader it gets cached.  Oddly enough, when we the check the box in Reader to open in the browser again the cached file is honored.

      Server: Windows 2008, IIS

      Client:  Vista, Adobe 9.3.2, IE 7.0.6.x

       

      I appreciate any help
