Server globals

[Ralph DiMola]

Using the IP can fail if more than one user is on the same IP via a router
using NAT. The Browser local storage is a better solution.

Hi Matthias,

It is user specific, but I just tried the saving to a text file on the
server -- very fast. Got the user IP from $_Server, and used that in the
filename for easy later retrieval. How much data can a cookie hold? Guess
I'll test that.

One of the reasons I'm fussing with this is I'm trying to come up with some
kind of pagination system. I'm probably trying to re-invent the wheel --
badly.

It's a simple membership list, with a few hundred records. Only want to show
30 on the page at a time. I wonder if anyone has a LC sample for doing that.
I tried Ralph Bitter's Revigniter but just can't wrap my head around it.

Using MySQL for testing, so could try to figure out using the CURSOR
feature. But know nothing about avoiding injection attacks, so may fall back
to using  a .csv for the datafile. I've done that for all my other
projects....

Anyway, thanks for the info; no global variables, but file saves look like
they'll work!

That will grant that the value is available  at all pages in the same
domain.

For the first time, I would like a global variable -- that is a variable
that would retain it's value even if the page is re-loaded. Or if a user
goes to another .lc page/file in the domain.
