tcl_site_nodes is used in only 1 place. It's supposed to be a cache of site node information, but it's implemented as a global var (which are global only to 1 interpreter), so it really doesn't do what it's supposed to do:
Slightly simplified code from rp_filter (in request-processor-procs.tcl)
global tcl_site_nodes
if [catch { array set node $tcl_site_nodes([ad_conn url]) }] {
array set node [site_node [ad_conn url]]
set tcl_site_nodes([ad_conn url]) [array get node]
}
The answer would be to make it an NSV, but I noticed that there's already an NSV that maintains this info properly (inside the
site_node call above). So, I can just get rid of tcl_site_nodes var, right? A patch is forthcoming...
