Hash Persistence based on HTTP Header "SV" tag

I might be wrong, but the documents on this one mentions cookies rather than headers:

Have you considered using the native cookie persistence, or perhaps a universal one if you insist on using the sv header?

Then you're in the right forum. 🙂

Must confess that I have not done this particular thing, but try this?

First create this irule:

when HTTP_REQUEST {
  if { [HTTP::header exists "sv"] } {
    persist uie [HTTP::header value "sv"]
  }
}

Then create a universal persistence profile and choose the irule you just created as "irule" in the configuration

Assign the persistence profile to the virtual server.

Worked like a charm. Here's how it looked like on my unit:

curl -k -H "sv: test" -H "Host: www.mysite.com" https://VIP-IP/en/

Sys::Persistent Connections
universal  test  VIP-IP:443  SERVERIP:4000  (tmm: 0)
Total records returned: 1

The default timeout is 180 seconds. Are you sure you tested before that?

If the sv header is set in the response as well as the request, please add an irule event from for

when HTTP_RESPONSE

like this:

when HTTP_REQUEST {
  if { [HTTP::header exists "sv"] } {
    persist uie [HTTP::header value "sv"]
  }
}

when HTTP_RESPONSE {
  if { [HTTP::header exists "sv"] } {
    persist add uie [HTTP::header value "sv"]
  }
}
