It's not a good idea to serve large PDF files through PHP. The Acrobat
Reader uses partial retrieval to allow a user to quickly jump to
different parts of a document. Unless you implement partial retrieval
yourself, or use the PEAR HTTP class, this functionality is disabled
and the user would have to wait for the whole document to finish
downloading.
