How to track / monitor changes in an on-line PDF file? Need to be notified when that happens.

May be you can retrieve something like the headers and see the modified date? but you will need a script to do that.

You could use the response of a service like http://www.rexswain.com/httpview.html

And read the line:


Probably there is no easy way to do it.

You can consider using LaTex for PDF creation - you will be able to track the "source code" of the PDF as any other source (SVN/Git/ etc.).

You can also use use the pyPdf lib to convert PDF contents to plain text (which is easily track-able).


Sounds like you're trying to use a basic version of source control. This might be a bit too large/complicated for your needs, but have you considered checking in the file to a CVS/SVN repository and then having the users access it through a web interface?
