[thelist] [OT] - geek of the week

[Jeremy Ashcraft]

(Sorry matt, I've got a good tip coming.........)

Please forgive the off-topic post, but this may interest a few folks on this 
list.....

Some of you from that "other" list from the old hotwired days may remember 
the Geek of the Week section they had in their members area.  I used to love 
that section and spent many an hour at work entering.  Anyway, in the spirit 
of the old GOTW,  I've created a Geek O' the Week contest of my own.  I'm not 
doing this to get people to visit my site.  I could really care less about 
that.  I just want to get people involved in something I thought was really 
cool and miss seeing. 

you won't get anything(yet) for winning, just the satisfaction of being King 
Geek for 7 days.  If you want to participate, head on over.  If not, that's 
cool too.  Here you go....

<tip type="php sessions">
Sessions on PHP(and I imagine ASP and JSP too) do not work properly in a load 
balanced server environment.  Say server X and server Y are 2 servers in a 
load balanced cluster.  A user connects to server X and create a session.  
The next request might go to server Y which has no knowledge of the session.  
An easy way to resolve this problem in PHP is to use the session_save_path() 
function.  Since the directory where PHP saves sessions is specified in the 
php.ini file and is usually /tmp or C:\TEMP, this is what causes the problem 
since both are seperate directories on 2 different boxes.  To solve this, 
find a shared directory that all load balanced servers have access to and 
create a tmp directory to store your sessions.  Use the session_save path 
function after your session_start() function call to set the session save pth 
to this new shared tmp directory.  There you go.  Load balancing and PHP 
sessions!!
