Create a directory on your IFS that is both set up as a NetServer share and is also configured as an accessible directory in your HTTP configuration file.
For example, our HTTP server configuration file includes a directive that enables the server to access the /wwwroot/htdocs directory of our IFS, where our PDFs are stored. We then set up a NetServer share to that same /wwwroot/htdocs directory that gave certain users access to the directory. Whenever an user with access to the directory updates a PDF, the changed document is then immediately available via the HTTP server.
If you have a program creating the PDF, you may not even need the NetServer share. You may just need to modify your HTTP server’s configuration file. Create a directive that points to the directory where the PDF is stored (/mypdffolder, for example), and you should then be able to access the document via your web browser by typing something like:
