Hi,
It sounds like you want an iRule to fire on a Response event and collect some part of the payload or headers (in HTTP for example). The iRule event and actions depend on the protocol and profiles in use. We couldn't advise anything more specific without knowing what your traffic is and where the data is in the payload you want to inspect.
Michael.

Hi Michael,
We are trying to write a iRule for the BIG-IP universal persistence module.
Our mission is to extract and persist from a HTTP response payload/body an application unique identifier (something like a seesionid for us).
Then use it in a consecutive HTTP requests.
Note, this unique identifier return in text/xml/soap-xml response formats and there is no cookie involve here.
We're having problem to write the TCL code for the extraction of our custom unique identifier from the HTTP response payload/body.
We have checked these manuals and did not find example for this kind of functionality:
https://clouddocs.f5.com/api/irules/HTTP_RESPONSE.html
https://clouddocs.f5.com/api/irules/HTTP__payload.html
https://clouddocs.f5.com/api/irules/HTTP_RESPONSE_DATA.html
https://clouddocs.f5.com/api/irules/HTTP__collect.html
https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/ltm_configuration_guide_10_0_0/ltm_rules.html1197203
can you help?
Thanks.
