SPUEditVar
SPUEditVar is a position-independent config.txt/ezproxy.cfg directive that can appear anywhere in config.txt/ezproxy.cfg.
SPUEditVar is used to assign values to variables that are used with SPUEdit directives. SPUEditVar can be used to establish site-specific values that are used in conjuction with generic SPUEdit rules for rerouting access to specific URLs.
Sample use:
SPUEditVar variable1= value1
SPUEditVar variable2= value2
Defined variables can be referenced in the replacement portion of SPUEdit directives with the syntax ${ variable}. You can use $e{ variable} for the variable's URL percent-encoded value.
