NimbostratusConfiguring Virtual Service to retry requests on timeout
Hi all,
I want to configure the following behaviour: if one server has not answered on http request in e.g. 1 second, the request will be resent to another server. Is it possible?

CirrusYou can configure your the pool attached to your Virtual Server to re-select a new pool member by changing the "Reselect Tries" to a value higher than 0. It will re-select a new pool member as many times as you configure there.
G_C_33937Thanks, Brad! Based on https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/ltm_configuration_guide_10_1/ltm_pools.html, Reselect Tries - Specifies the number of times that the system tries to contact a new pool member after a passive failure. 1 question: what means passive failure? 2 question: there is no possibility to specify the time out, am i right?- Brad_ParkerThere is no timeout configured, a handshake failure would result in pool re-selection.
- Brad_ParkerThis previous post suggests the failure to receive data timeout would most likely be configured using the SYN retransmission in your server-side TCP profile. https://devcentral.f5.com/questions/pool-reselect-tries-user-specified-interval- . I'm inclined to agree.
