Finally, may I ask a question? In my case, all of the PDFs that generated
from MS Word + Acrobat can be upload with the content-length=512KB, but the
PDFs generated from PageMaker, its content-length is greater than 512KB, why
the content-lengths are different?
Probably because they use two different libraries to produce the PDF. It is an open standard and there are a handfull of different libraries out there.
Sorry for my poor english.
Thanks for your help.
