2 request.add_variable(
3 tbl, -- table where the variable is stored
4 key, -- name of variable (key within the table)
5 value -- optional value for initialization
6 )
8 Marks a field of a table to be re-initialized for every request. If this variable (i.e. the field of the table) is modified before the first requst is being handled (e.g. during configuration or pre-/post-fork initializers), then the modified value will be used for re-initialization on every request. See env/request/__init.lua for an example.
