NimbostratusF5 injects a CSPM script in the response when we have Page Load Time option in BIG-IP Analytics. The subject script was injected in the HEAD tag of the HTML response. We have some metadata in the HEAD tag which we need to be move on top of the f5_cspm script before the response is send to the client.
Can we use an iRule to do this if possible. You help is much appreciated.
Employeenot sure if this is usable. anyway, html content profile is introduced in 11.4. we can use it to prepend and remove html tag (i.e. add new html tag and delete the old one).
e.g.
root@(ve11-8)(cfg-sync In Sync)(Active)(/Common)(tmos) list ltm virtual bar
ltm virtual bar {
destination 172.28.24.201:80
ip-protocol tcp

pool foo
profiles {
cspm { }
http { }
myhtml { }

}

}

NimbostratusHi Nitass,
Thank you for the response. I think this what I am looking for.
