Http::retry after timeout (again)

Hi Serge,

I do strongly believe, that you have to request your backend systems entirely through SIDEBAND connections, so that you're able to transperently reselect/retry an successfully established - but then somehow stalled server side connection.

The idea behind this approach is, that SIDEBAND connections do provide independend timeouts for the connection establishment (comparable to the LB_FAILED detection) and the received payload (the added functionality you're looking for).

Note1: Using SIDEBANDs to retrieve the content would unfortenately have a strong impact on your performance... 😞

Note2: You may also investigate if your application / web server already supports a configurable maximum response timeout, so that it would send a "503 - Server Busy" response to your your F5 after the given timeout is reached. The 503 response could then be catched during the HTTP_RESPONSE followed by a

[LB::down]

[HTTP::retry]

Cheers, Kai
