I'm trying to understand what you want to do. From what you said I'm
guessing that you want a portable way to generate unique keys for a
cache, and are looking to some implementation of UUID to do this. [see
http://tools.ietf.org/html/rfc4122]
I already have that GUID/UUID part, see
http://www.expresslanevideo.com/docs/guid.txt (I am sure there are
better implementations, and I am open to suggestions.)
The problem I am having is easy implementation for a web based system.
For version 1.0, I was using memcached to hold this object between
users/browsers/sessions for up to 30 minutes after the last hit, so that
I would only have one object available to all users.
There are two problems with this implementation
(1) memcached introduces more complication to the programmer **
(2) not all web hosts support memcached (although I asked blue host last
night if they do and they said yes)
I have updated this class to be a singleton class because of the
efficiency of the singleton programming pattern, but that doesn't help
with holding objects between users/browsers/sessions, because the web
server seems to drop all classes and objects after each page load.
** Note: I just thought of a way to help with this, I could memcached
code into the class to reduce complications for the programmer. This
doesn't help with the second point though.
Thank you,
Justin Giboney
