Ideal place for wp-cron / noabort rule?

Hi, I'm trying to find the right place to set a rule like this one (taken from the LiteSpeed docs):

SetEnvIf Request_URI "(wp-cron).php" noabort noconntimeout

Would this fit into the Rewrite Tab > Rewrite Rules section or is something like this considered a "document root level rewrite rule" which should be placed under Context?

PS, registration for the LiteSpeed forums doesn't work at the moment (403). I've contacted them, but that's why I'm asking here.
