Depending of how you're using global variables and Midgard version, you could:
1) Add its value as a query parameter (/foo/bar.html?variable=value),
then check in code-global !isset($variable) for setting default
value. (Works in any Midgard version)
2) Store global value as extensible record field with some
session-specific value and pass this value as query info
(/foo/bar.html?sessionid=value), then retrieve extensible record field
with name based upon sessionid -- works for versions >= 1.4beta3
3) Create anonymous user for visitor, store value in person's fields
(see personalization in Manual for more), and pass person's ID as
session value (using active pages it could be like constructing pages
with /foo/{personid}/bar.html where {personid} is value of person ID,
for example -- /foo/6321/bar.html). Then use $argv/$argc in
code-global for selecting correct session (in this case -- person ID).
(Works in any Midgard version)
