HSL asynchronous HSL::send
1 Topic
HSL logging fully asycnronous? Using HSL::send via iRule - will it pause http processing of request?
Hi - we have a vendor who will be seeking to integrate an iRule which leverages HSL to send logging; the immediate destination will be an HTTP virtual server which we will establish (which will, in turn, proxy the request to their cloud endpoint, using TLS for that leg of the journey). This vendor iRule will be added to various virtual servers, in order to log the request and response for all user requests against those virtual servers. In such a circumstance, will the HSL::send command in the vendor iRule behave synchronously, waiting for an HTTP response before allowing the continued HTTP processing of the user request? Or, does HSL automagically behave in an asynchronous fashion (even in such a circumstance, where the destination of the logging is an HTTP virtual server, requiring TCP)? I implicitly assumed that part of the "high speed" for a typical HSL syslogging capability was that it was just throwing UDP packets at port 514 out there somewhere :-). Thank you.Solved639Views0likes4Comments
