Global variables, affinity, and sessions w/o cookies,

Hi,

Thanks for mod_ruby 1.20.  It's great!

I have several questions (some might consider feature requests):

1. Is it possible to set a global variable that is consistent across all 
Apache processes?  I realized that I have 5 different global variables 
of the exact same name (a simple counter) because I have 5 Apache 
processes that appear to have their own mod_ruby instance.

2. Is it possible to set server/browser "affinity" so that whenever 
possible, the same client accesses the same Apache process repeatedly 
instead of round-robin?  Something like "wait", "error" or "use-any" as 
options in case the same process isn't immediately available.

If this isn't available with mod_ruby, do you know if there are Apache 
mods that enable affinity?

3. We're designing a dynamic site using mod_ruby + eruby that supports 
browsers without javascript or cookies.  Do you recommend any particular 
method, library or tools to handle sessions?  I'm guessing 
url-rewriting.  Would appreciate your thoughts & recommendations.

Thanks again for giving us mod_ruby and eruby!
