need some help with a AS3 declaration

See the article below of how to declare objects in the shared as3 folder under the partition like pools:

Solved: AS3 referencing objects across applications - DevCentral (f5.com)

If the 2 apps/virtual servers are in the same tenant you can try the "use:" pointer to define the pool outside of the 2 virtual servers in the AS3 declaration

BIG-IP AS3 Declaration Purpose and Function (f5.com)

"persistenceMethods": [ {"use": "mypersist"} ]
"mypersist": {
    "class": "Persist",
    "persistenceMethod": "cookie",
    "cookieName": "MYCOOKIE"
}

Other than that for certficates I have not tried using url but I saw:

TLS Encryption (f5.com)
