How to view session table created with iRule

I tested your config in my box now and it worked, but I have a feeling that we might run different versions. I'm running 11.5.3.1.0.167 Hotfix 1.

That said I'm about to run out of ideas.

Try this rule to see if there actually is any content?

when HTTP_REQUEST {

    set response ""

    foreach tablename [table keys -subtable "metatable"] {
        foreach key [table keys -subtable $tablename] {
            set value [table lookup -notouch -subtable $tablename $key]
            set response "$response
$key = $value"
        }
    }

    HTTP::respond 200 content "$response"
    log local0. "HTTP RESPONSE: $response"
}
