I would like to say that I am not well at F5 iRule so I would like to get some advise from you guys.

I am testing with enabling/disabling certain feature of webpages when a user is coming from a specific geographic location. For the test purpose, the testers want me to get a specific area like New south Wales inserted into header rather tan the true location.

At this moment, the following irule is configured on the dev F5.

when HTTP\_REQUEST { HTTP::header insert X-UBET-Region [whereis [IP::client\_addr] state]

Could you please give me a right direction on this request? Thank you in advance.

Hi

Rather than do a GEO lookup, you could just add the header using whatever value you like, so something like

```tcl
when HTTP_REQUEST { 
HTTP::header insert X-UBET-Region "My Region"
}

```

Or, if you wanted to be a bit more granular, you could look for some other information, such as the Dev team’s source IP/VLAN and then only apply the updated header.

```tcl
when HTTP_REQUEST {

if { [IP::addr [IP::client_addr] equals 10.10.10.0/24] } {
HTTP::header insert X-UBET-Region "My Region"
} else {
HTTP::header insert X-UBET-Region [whereis [IP::client_addr] state]
}
}

```
