HTTP:enable_auto(code)

This command is same as HTTP:disable_auto(), but it does the opposite task. By default, all the events are automatically enabled after disable_event() is called. So we only need to call this to undo earlier calling of disable_auto(). See the example in disable_auto() section above.

Example

In this example, code 0x2 means HTTP_RESPONSE event, once we disable it, the corresponding event function will not be called for this request. Once we call disable_auto() with the same code, it will continue disabled until enable_auto() is called.

when RULE_INIT {
    count = 0
}
when HTTP_REQUEST {
    count = count+1
    if count>3 then 
        count=1
    end
    debug("==> begin REQUEST scripting: count=%d\n", count)
    -- Disable RESPONSE event (code == 0x2)
    code = 0x2
    if (count == 1) then
        debug("==> disable_event: count=%d\n", count)
        HTTP:disable_event(code)
        --Also disable automatic enabling for the next request
        HTTP:disable_auto(code)
    end
    if (count == 2) then
        -- Enable it for the third one.
        HTTP:enable_auto(code)
    end
    debug("==> end REQUEST scripting.\n\n")
}
when HTTP_RESPONSE {
    debug("=====> begin RESPONSE scripting: count=%d\n", count)
    debug("=====> end RESPONSE scripting.\n\n")
}
