irule executes twice when refreshing a website

Hi ekaleido, this actually made my website unavailable for some reason...

error "connection reset" in chrome...

Using the following modifications? What is being logged?

when HTTP_REQUEST {
  log local0. "-------------------------------------------------------------"
  log local0. "Path [HTTP::path]"
  if { not ([HTTP::path] starts_with "/api/") } { return }
  set apiType [lindex [split [HTTP::path] "/"] 2]
  log local0. "api type $apiType"
  append newSubdomain $apiType .uat.
  log local0. "New Subdomain $newSubdomain"
  HTTP::header replace "Host" [string map [list "api-uat." $newSubdomain ] [HTTP::host]]
  log local0. "-------True"
  HTTP::path [string map [list "/api/$apiType" "/api"] [HTTP::path]]
  log local0. "New Path [HTTP::host][HTTP::path]"
  unset $newSubdomain
}

the error was

warning: [variable reference used where variable name expected][$newSubdomain]

so I changed

unset $newSubdomain

to

unset newSubdomain

and it seems to be working.

Thanks! 🙂

a question... Why would irule require a variable to be unset? shouldn't all local variable be unset at the end of the script? as far as I know this is a local variable...

Oddly enough, the variables don't get reset by default. This is especially annoying if you reuse variable names across iRules and they step on each other. :(

I see! thanks a lot for your help... i'm pretty sure this is a bug!
