Dominic Veit wrote: We have recently run into a problem with Internet Explorer that was not covered in your book. This chapter has saved us in many other cases. I thought you may want to add this new scenario to a subsequent version of the book.The problem is the IE 'blank page' problem, and it was caused by our including a cache-control header in the PDF response:
Cache-control: no-cache="set-cookie, set-cookie2"
In our case, this header was added by a filter, and it was resolved by implementing an ignore list to the filter. IE does not like the set-cookie in the following header, and this will cause it to drop PDFs.

AWI stands for Approved Work Item. It's a status prior to a Working Draft. In January 2011, ISO 14289 was in the DIS stage: "Draft International Standard." It was discussed in the ISO meeting in Salt Lake City in May 2011. Normally, there should be an FDIS in the Summer of 2011: a Final Draft International Standard. If all goes well, the standard should be approved in the Fall.
