Access local variable from a different Virtual Server

Is it possible to move a local variable between Virtual Servers without using a global variable or the session table. I have one tried to transfer it via the session table but as one Virtual Server is calling the second Virtual Server the variable is not in the session table when the second Virtual Server tries to get it.

    Hello,

    Did you try this with sharedvar? https://clouddocs.f5.com/api/irules/sharedvar.html

    Example:

    # Applied on external layer vs
when HTTP_REQUEST {
    sharedvar my_shared_var
    set my_shared_var "It was defined at [virtual name]"
 
    log local0. "Running: [virtual name]"
    log local0. " ${my_shared_var}"
    
    # Move to internal vs
    virtual vs_internal
}
    # Applied on internal layer vs
when HTTP_REQUEST {
    sharedvar my_shared_var
    
    log local0. "Running: [virtual name]"
    if { [info exists my_shared_var] } {
        log local0. " ${my_shared_var}"
    }
}

    Regards.
