Data returning from the ICAP server may hang while an ICAP_RESPONSE event is pending on the internal virtual server.
HTTP client does not receive the complete response. Eventually the ADAPT filter on the parent virtual server will time out and perform its service-down-action.
A long-running iRule command executes asynchronously in the ICAP_RESPONSE event.
This issue has no workaround at this time.
Data flow from the ICAP server to the HTTP client resumes after the ICAP_RESPONSE event is complete.
