iRule URI rewrites don't always use the correct pool
- Nov 01, 2024
dra1nbama9e Can you please provide the configuration of your virtual server that this is associated to? My guess currently is that that host was sent to the incorrect pool previously and when the new request came in again for the new path it went to the old pool. You can try configuring a /32 OneConnect profile and configuring it on the virtual server in question to see if that corrects the issue.
Adding the logs and config here as well.

}
can you verify that this part is ok?
it seems different from examples in https://wiki.tcl-lang.org/page/string+map
.............
elseif { [HTTP::uri] starts_with "/api" } {
set uri [string map [list "/api" "" ] [HTTP::uri]]
HTTP::uri $uri
pool example.com_http_9241_pool
}
.........
