BIG-IP : irule : add request header ( replace if exists )
F5 BIG-IP Virtual Edition v11.4.1 (Build 635.0) LTM on ESXi
I need to add/replace a specific request header. Here's my iRule :
when HTTP_REQUEST {
if { [HTTP::header exists "original-uri"] } {
HTTP::header replace original-uri [HTTP::uri]
} else {
HTTP::header insert original-uri [HTTP::uri]
}
}
Is there a way to perform the insert/replace in a single line ?

can't you just remove (HTTP::header remove) and then insert (HTTP::header insert)?
- for case where header is not present : would [HTTP::header remove] throw an error ?
- nitassno
- so why does [HTTP::header replace] command exist ?
