AltostratusAPM AdAuth HTTP Header Insert iRule Switch Statement
EmployeeAs Jason said, there are many ways to do this and your method looks fine. But note your typo in IP::client_addr. And it is good practise to use -- to terminate switch options.
You could also do this by checking whether the header already exists
when ACCESS_ACL_ALLOWED
{
if { ! [HTTP::header exists iv-user] } {
HTTP::header insert "iv-user" [ACCESS::session data get "session.logon.last.username"] }
}
}
AltostratusThanks for the response! Yes, that was me fat fingering it here, code I've written up/exists currently does not have that typo. So to clarify your comment on switch termination, it would be as follows then:
when ACCESS_ACL_ALLOWED
{
switch [IP::client_addr]{
"10.0.0.1" -
"10.0.0.2" -- { //do nothing }
default {
HTTP::header insert "iv-user" [ACCESS::session data get "session.logon.last.username"] }
}
}I like that code you have provided for checking existing headers, really appreciate the options here.

Hiya, when I mentioned the switch termination i meant this ie the -- after the switch command
when ACCESS_ACL_ALLOWED { switch -- [IP::client_addr] { "10.0.0.1" - "10.0.0.2" { //do nothing } default { HTTP::header insert "iv-user" [ACCESS::session data get "session.logon.last.username"] } } }- tdaish
Doh! My bad, thanks for that. I did find that the F5 does not like:
// do nothingwithin those braces, so I have omitted the contents and left it as:
when ACCESS_ACL_ALLOWED { switch -- [IP::client_addr] { "10.0.0.1" - "10.0.0.2" {} default { HTTP::header insert "iv-user" [ACCESS::session data get "session.logon.last.username"] } } }This should be okay right?
