[FX.php List] Capturing IP for a choice calc

Wed Mar 1 10:51:11 MST 2006

We have other information that would be displayed that is not  
copyrighted. It is only the link that leads to a pdf that can only be  
viewed in-house. I would not want to lock out users from being to  
view the non-copyrighted stuff. If while a user came to one of our  
branches and copied the URL down as you suggested, then it kind of  
sounds like I need a two-pronged approach, one to prevent the URL  
from working, and the other to prevent the link from showing, when  
accessed outside our network.

My project involves creating a digital library that gives online  
access to newspaper clippings and other records that have been  
collected since the early 1900's. Our staff is indexing everything  
into a FMP database, and we are scanning and creating pdfs of all of  
these clippings. The pdfs are accessed from a link that is stored in  
the database. There is no copyright issues involved with a good  
portion of the material. The clippings that are from our local  
newspaper are copyrighted by them and they have only given us  
permission to share their materials only with patrons when they are  
in one of our branches.

We do have a proxy server that allows our patrons access to some of  
our other restricted databases. They have full access to them only  
after entering their library card number and name. Unfortunately,  
that approach will not work for us, as we do want the general public  
to have access to everything we don't have copyright issues with.

Maybe it would help if I give everyone a better example of what I'm  
trying to do. If you want, go to:

http://fmcwp.sjcpl.org/1875Atlas/index.php

While this is not the pages I want to protect, the layout and general  
operation will be similar to my copyrighted project. When you drill  
down to a detail page at the bottom there is a link to access a pdf  
of the image. Image that some of the records needed to be restricted,  
(due to copyright), in a way that you could only see that link if you  
were in our library and if you were accessing the pages from outside,  
the link would be replaced by a phase explaining why and where they  
could view the pdf, (or even the real article).

My part of the project is basically done, the FMP database, and the  
FX.php web pages, but as I have already stated, I still learning php,  
so I don't really don't how to do this part of the code.

Thanks,

Peter
